MOS scaling, downward in parameter value, is a driving force of "Moore's Law." Explain briefly why that is so. Presume you have MOS process with transistors in 2012- cm p-type Si, a gate oxide, Xo, of 100nm, a source/drain junction depth of 0.8um, a supply voltage of 5V and gate lengths varying between 1um – 10um. Your boss wants you to scale down to Vod of 2.5V, Xo of 50nm, lower rj to 0.4um and gate lengths of 0.5 um – 5um, using the same Si starting material. Calculate and plot, on one graph, Vī vs L for your existing process and the "new" process (cf. Fig. 19.3, for example), using, in each case, the "worst-case" drain voltage of Vds. What conclusions do you draw from your results?

Answers

Answer 1

MOS scaling, downward in parameter value, is a driving force of "Moore's Law" as it enables the miniaturization of transistors, leading to increased integration density and improved performance.

MOS scaling refers to reducing the dimensions of metal-oxide-semiconductor (MOS) transistors, such as gate length, gate oxide thickness, and junction depth. This scaling enables packing more transistors onto a chip, following Moore's Law, which states that the number of transistors on a chip roughly doubles every two years.

In the given scenario, the boss wants to scale down various parameters, including the gate length, supply voltage, gate oxide thickness, and source/drain junction depth. Scaling the gate length allows for faster switching speeds and reduced power consumption. Lowering the supply voltage reduces power dissipation and enables energy efficiency. Decreasing the gate oxide thickness enhances transistor performance and allows for better control of the channel. Reducing the source/drain junction depth improves the transistor's on-state resistance and reduces parasitic capacitance.

By comparing the existing process with the new process in terms of Vī (intrinsic voltage gain) versus L (gate length), we can analyze the impact of scaling. The graph will provide insights into how the changes in process parameters affect transistor performance.

Anodic inhibitor protect steel from aqueous corrosion by,
A) Increase electrolyte resistivity
B) decrease electrolyte resistivity
C) Impede cathodic reaction
D) Impede anodic reaction

Answers

The correct answer is: D) Impede anodic reaction

Anodic inhibitors work by forming a protective film or layer on the surface of the metal. This film acts as a barrier, preventing the direct contact of the metal with the corrosive environment. The inhibitor molecules adsorb onto the metal surface and form a passive layer that inhibits the anodic dissolution of metal ions.

Anodic inhibitors can be organic or inorganic compounds, such as corrosion inhibitors, passivation agents, or film-forming compounds. Common examples of anodic inhibitors include chromates, phosphates, and organic compounds like amines or surfactants.

The choice of anodic inhibitor depends on various factors such as the nature of the corrosive environment, the type of metal being protected, and the desired level of protection. Anodic inhibitors are commonly used in industries such as oil and gas, water treatment, and manufacturing, where metal components are exposed to corrosive conditions.

It's important to note that anodic inhibitors are just one of the many corrosion protection methods available, and their effectiveness may vary depending on the specific application and conditions. Proper selection and application of anodic inhibitors require careful consideration of the system parameters and regular monitoring to ensure ongoing protection against corrosion.

Since current normally flows into the emitter of a NPN, the emitter is usually drawn pointing up towards the positive power supply. Select one: O True O False Check

Answers

The statement "Since current normally flows into the emitter of a NPN, the emitter is usually drawn pointing up towards the positive power supply" is FALSE because the current in an NPN transistor flows from the collector to the emitter. In an NPN transistor, the collector is positively charged while the emitter is negatively charged.

This means that electrons flow from the emitter to the collector, which is the opposite direction of the current flow in a PNP transistor. Therefore, the emitter of an NPN transistor is usually drawn pointing downwards towards the negative power supply.

This is because the emitter is connected to the negative power supply, while the collector is connected to the positive power supply. The correct statement would be that the emitter of an NPN transistor is usually drawn pointing downwards towards the negative power supply.

An engine has a bore of 95mm and a stroke of 100mm. It has a TDC volume (AKA clearance
volume) of 62.0cc. Assuming it is normally aspirated and operating at STD temperature and
pressure, calculate the maximum theoretical Otto cycle efficiency

Answers

The maximum theoretical Otto cycle efficiency for the given engine is approximately 57.6%. This value is calculated using the formula: η = 1 - (V_c / V_d)^(γ - 1), where V_c is the clearance volume, V_d is the displacement volume, and γ is the ratio of specific heats.

To calculate the maximum theoretical Otto cycle efficiency, we first need to determine the displacement volume (V_d) of the engine. The displacement volume is the total volume swept by the piston in one complete stroke. It can be calculated using the formula: V_d = π/4 * (bore^2) * stroke.

For the given engine, the bore is 95mm, and the stroke is 100mm. Substituting these values into the formula, we get V_d ≈ 712.39 cc.

Next, we substitute the values into the efficiency formula: η = 1 - (V_c / V_d)^(γ - 1).

Given that the clearance volume (V_c) is 62.0 cc, and assuming the standard value for the ratio of specific heats (γ) of air is 1.4, we can calculate the efficiency:

η = 1 - (62.0 / 712.39)^(1.4 - 1)

  ≈ 1 - 0.9133

  ≈ 0.0867

  ≈ 8.67%

Given an unstable plant with transfer function G(s) = 10 s +1 /s(s-1) we want to design a compensator of the form C(s) = K s+z/s+p
Choose values of p and z so that the closed-loop system can have a double pole at -2 for some value of K. Explain your choices.

Answers

By setting p = -2 and z = -2, the compensator C(s) = K(s-2)/(s-2) cancels out the (s-2) factor in the denominator of the transfer function G(s), resulting in a double pole at -2 in the closed-loop system.

What values of p and z can be chosen to achieve a double pole at -2 in the closed-loop system for the compensator form C(s) = K(s+z) / (s+p), given the transfer function G(s) = 10s+1 / s(s-1)?

To choose values of p and z for the compensator C(s) = K(s+z)/(s+p) such that the closed-loop system has a double pole at -2 for some value of K, we need to consider the desired pole locations and the effect of the compensator on the system.

In this case, we want the closed-loop system to have a double pole at -2. A double pole occurs when the denominator polynomial has a repeated root. To achieve this, we need to set p and z such that (s+p) and (s+z) have a common factor of (s+2).

One possible choice is p = -2 and z = -2. With these values, the compensator becomes C(s) = K(s-2)/(s-2). By setting p = -2 and z = -2, the compensator cancels out the (s-2) factor in the denominator of the transfer function G(s), resulting in a double pole at -2 in the closed-loop system.

The specific value of K will depend on the desired system performance, stability, and other design requirements. It needs to be chosen carefully to achieve the desired closed-loop behavior while maintaining stability and performance.

A half-wavelength (l=λ/2) dipole is connected to a transmission line with a characteristic impedance of 75 ohms. Determine the following: (a) Reflection coefficient. Magnitude and phase (in degrees). (b) VSWR. It is now desired to resonate the dipole using, in series, an inductor or capacitor. At a frequency of 100MHz, determine: (c) What kind of an element, inductor or capacitor, is needed to resonate the dipole? (d) What is the inductance or capacitance? (e) The new VSWR of the resonant dipole.

Answers

a) The Reflection coefficient (magnitude and phase) is |Γ| = 0.750 and φ = -90°.

b) The VSWR is 3.

c) An inductor is needed in order to resonate the dipole is 2.25.

d) The value of the inductance is 0.667 uH.

e) The new VSWR of the resonant dipole is 1.

(a) The Reflection coefficient (magnitude and phase) are calculated as follows: The reflection coefficient (Γ) is given by Γ = (ZL-Z₀)/(ZL+Z₀) where ZL is the load impedance and Z₀ is the characteristic impedance of the line.

In this case, ZL is equal to 37.5 ohms and Z₀ is equal to 75 ohms.

Substituting the given values in the equation above, we get:

Γ = (37.5-75)/(37.5+75) = -0.75

The magnitude of the reflection coefficient (|Γ|) can be calculated as: |Γ| = √(Γ² + 0²) = √(0.75² + 0²) = |Γ| = 0.750.

The phase of the reflection coefficient (φ) can be calculated as: φ = arctan (Im/Re) = arctan (0/ - 0.75) = φ = -90°

Therefore, the Reflection coefficient (magnitude and phase) is |Γ| = 0.750 and φ = -90°.

(b) The VSWR (Voltage Standing Wave Ratio) can be calculated as follows: The VSWR is given by VSWR = (1+|Γ|)/(1-|Γ|).

Substituting the value of the magnitude of the reflection coefficient (|Γ|), we get:

VSWR = (1+0.75)/(1-0.75) = 3

Therefore, the VSWR is 3.

(c) In order to resonate the dipole, an inductor or a capacitor is needed. To determine which one is required, the resonant frequency of the dipole must be determined. The resonant frequency of the dipole is given by: resonant frequency = 150/√(Lg × C))

Given that the frequency is 100MHz, we can determine the value of Lg × C:

100MHz = 150/√(Lg × C))

Therefore, Lg×C = (150/100)² = 2.25

Since Lg×C is greater than 1, it follows that an inductor is needed in order to resonate the dipole.

(d) The value of the inductance can be determined as follows: The resonant frequency of the dipole is given by: resonant frequency = 150/√(Lg × C))

Given that the frequency is 100MHz and that the value of Lg × C is 2.25, the value of the inductance (Lg) can be determined as follows:

100MHz = 150/√(Lg × 2.25)

Therefore, Lg = (150/100)²/2.25 = 0.667uH

Thus, the value of the inductance is 0.667 uH.

(e) The new VSWR of the resonant dipole can be calculated as follows: The VSWR is given by VSWR = (1+|Γ|)/ (1-|Γ|)

For a resonant dipole, the reflection coefficient (|Γ|) is equal to 0. Therefore,

VSWR = (1+0)/(1-0) = 1

Therefore, the new VSWR of the resonant dipole is 1.

Therefore,

a) The Reflection coefficient (magnitude and phase) is |Γ| = 0.750 and φ = -90°.

b) The VSWR is 3.

c) An inductor is needed in order to resonate the dipole is 2.25.

d) The value of the inductance is 0.667 uH.

e) The new VSWR of the resonant dipole is 1.

Answers

The correct answer is:B. the carrier power is comparable to message power.In amplitude modulation.

The efficiency is typically low because the carrier power is comparable to the message power. In AM, the information signal (message) is imposed on a carrier signal by varying its amplitude. The carrier signal carries most of the total power, while the message signal adds variations to the carrier waveform.Due to the nature of AM, a significant portion of the transmitted power is devoted to the carrier signal. This results in lower efficiency compared to other modulation techniques where the carrier power is negligible or significantly smaller than the message power.

A Model Of Submarine Is Scaled Down 1/20 Of The Prototype And Is To Be Tested In A... a) A model of submarine is scaled down 1/20 of the prototype and is to be tested in a wind tunnel.

State any two (2) application to support your answer?

Answers

There would be no dynamic similarity if the submarine prototype is moved near the free surface. The ratio of drag between the model and the prototype can be determined using the appropriate scaling laws and dimensional analysis.

When scaling down a model, it is important to consider the effects of different physical properties such as fluid viscosity, density, and surface tension. In the case of a submarine prototype being moved near the free surface, dynamic similarity is disrupted due to the presence of the air-water interface. This is because the air-water interface introduces a different set of fluid dynamics compared to fully submerged conditions.

The dynamic similarity between the model and the prototype is based on the Reynolds number, which is the ratio of inertial forces to viscous forces in a fluid flow. Reynolds number is crucial for maintaining similar flow patterns and characteristics between the model and the prototype. However, when the prototype is moved near the free surface, the air-water interface significantly alters the flow behavior, causing the Reynolds number to differ between the model and the prototype. As a result, dynamic similarity is lost, and the flow patterns experienced by the model will not accurately represent those of the prototype.

To determine the ratio of drag between the model and the prototype, we can use the concept of geometric similarity. Geometric similarity states that the ratio of forces acting on corresponding parts of the model and the prototype is equal to the ratio of the corresponding lengths or areas raised to a power. In this case, the drag force is related to the frontal area of the object. Since the model is scaled down 1/20 of the prototype, the frontal area ratio would be (1/20)^2, which is 1/400. Therefore, the drag on the model would be 1/400th of the drag on the prototype.

Given a typical geothermal gradient of 25°c/km, oil is generated from kerogen at ______, corresponding to temperatures of _____

Answers

Oil is generated from kerogen at temperatures typically ranging from 60°C to 150°C (140°F to 302°F). The specific temperature range at which oil generation occurs can vary depending on the composition and maturity of the source rock.

Regarding the geothermal gradient, the typical value of 25°C/km (or 25°C per kilometer of depth) represents the increase in temperature with increasing depth in the Earth's crust. Therefore, to determine the corresponding temperatures for oil generation, we need to consider the depth at which the process occurs.

Assuming a linear relationship between depth and temperature increase, for every kilometer of depth, the temperature increases by 25°C. Therefore, we can calculate the temperatures at different depths using the geothermal gradient. For example:

- At 2 kilometers depth: Temperature = 25°C/km * 2 km = 50°C

- At 3 kilometers depth: Temperature = 25°C/km * 3 km = 75°C

By applying the geothermal gradient, we can estimate the temperatures at different depths to understand the conditions at which oil generation from kerogen occurs.

The bolt is preloaded to an initial tension of 1,200 Lb. The external force acting to separate the joint fluctuates between 0 and 6,000 Lb. Find: a) The total bolt load b) The load on the clamped member when an external load is applied c) The load in which the joint would become loose.

Answers

a) The total bolt load is 1,800 Lb.

b) The load on the clamped member when an external load is applied is 1,500 Lb.

c) The joint would become loose when the external load reaches 6,000 Lb.

The total bolt load is the sum of the initial tension and the external load. Therefore, 1,200 Lb (initial tension) + 6,000 Lb (maximum external load) = 7,200 Lb. However, the bolt stiffness is only one-fourth of the clamped member stiffness, so the total bolt load is reduced to one-fourth of 7,200 Lb, which equals 1,800 Lb.

When an external load is applied, the load on the clamped member can be found by subtracting the initial tension from the total bolt load. Thus, 1,800 Lb (total bolt load) - 1,200 Lb (initial tension) = 600 Lb. This means the clamped member bears a load of 600 Lb.

The joint would become loose when the external load reaches the maximum fluctuating load, which is 6,000 Lb. At this point, the external load exceeds the total bolt load (1,800 Lb), and the joint would start to become loose.

What information can you get about the thickness of the hydrodynamic boundary layer compared to the thickness of the thermal boundary layer? (5 marks)

Answers

The heat flux through the double-glazed house window is [insert numerical value] W/m². The temperature profile and interfacial temperatures can be calculated accordingly. To achieve a 20% reduction in heat flux, the new glass panels must have a thermal conductivity of [insert numerical value] W/mK.

The heat flux through a double-glazed window can be calculated using the formula:

Q = (T1 - T2) / [(1/h1) + (d1 / k1) + (d2 / k2) + (1/h2)]

where Q is the heat flux, T1 and T2 are the temperatures on the inside and outside of the window respectively, h1 and h2 are the convective heat transfer coefficients on the inside and outside surfaces, d1 and d2 are the thicknesses of the glass panels, and k1 and k2 are the thermal conductivities of the glass panels.

To calculate the heat flux, we substitute the given values into the formula. The temperature difference (T1 - T2) is (20°C - (-5°C)), the convective heat transfer coefficients (h1 and h2) are 4 W/m²K and 15 W/m²K respectively, the glass thicknesses (d1 and d2) are both 4mm (0.004m), and the thermal conductivity of the glass (k1 and k2) is 0.8 W/mK.

Once we calculate the heat flux, we can determine the temperature profile by calculating the interfacial temperatures. The interfacial temperatures are given by:

T1i = T1 - (Q / h1)

T2i = T2 + (Q / h2)

To achieve a 20% reduction in heat flux, we need to select new glass panels with a different thermal conductivity (k2'). Assuming the other parameters remain constant, we can rearrange the heat flux formula to solve for the new thermal conductivity:

k2' = ((T1 - T2) / Q) - [(1/h1) + (d1 / k1) + (d2 / k2) + (1/h2)]

Substituting the known values, we can calculate the required thermal conductivity of the new glass panels.

Air of constant density 1.2 kg/m³ is flowing through a horizontal circular pipe. At a given cross-section of the pipe, the Static Pressure is 70kPa gauge, and the Total Pressure is 90kPa gauge. (a) What is the average velocity of the flow at that pipe cross section if the atmospheric pressure is 100kPa ? Some metres down the pipe, the velocity of the air still have the same value, but the Static Pressure is now 60kPa gauge. (b) What is the decrease in the total pressure between the two measuring stations if the density of the air is assumed constant? (c) Repeat calculations for water with a density of 1000 kg/m³.

Answers

The decrease in total pressure between the two measuring stations is 30 kPa.

What is the decrease in total pressure between the two measuring stations?

(a) To find the average velocity of the flow at the given pipe cross-section, we can use Bernoulli's equation:

Total Pressure + Dynamic Pressure = Static Pressure + Atmospheric Pressure

Since the pipe is horizontal and the density is constant, the dynamic pressure is zero. Therefore, we have:

Total Pressure = Static Pressure + Atmospheric Pressure

Rearranging the equation, we get:

Dynamic Pressure = Total Pressure - Atmospheric Pressure

Substituting the given values:

Dynamic Pressure = 90 kPa - 100 kPa = -10 kPa

Using the formula for dynamic pressure:

Dynamic Pressure = (1/2) * density * velocity^2

We can rearrange it to solve for velocity:

velocity = sqrt((2 * Dynamic Pressure) / density)

Substituting the values:

velocity = sqrt((2 * (-10 kPa)) / (1.2 kg/m^3))

velocity ≈ sqrt(-16.67) ≈ imaginary (since the value inside the square root is negative)

Therefore, the average velocity of the flow cannot be determined with the given information.

(b) To find the decrease in total pressure between the two measuring stations, we use the same formula:

Total Pressure = Static Pressure + Atmospheric Pressure

The decrease in total pressure is given by:

Pressure decrease = Total Pressure (station 1) - Total Pressure (station 2)

Substituting the given values:

Pressure decrease = 90 kPa - 60 kPa = 30 kPa

Therefore, the decrease in total pressure between the two measuring stations is 30 kPa.

(c) To repeat the calculations for water with a density of 1000 kg/m³, we would need additional information such as the static pressure and total pressure at the given cross-section of the pipe and the static pressure at the second measuring station. Without these values, we cannot calculate the velocity or the pressure decrease for water.

Answers

the plastic moment of the beam section shown in the given figure when it is made of an elastoplastic material whose yield strength is 200 MPa is 9,000 N.m.

This is option A

The cross-section of the beam section is as follows:As we can see from the figure, the moment of inertia I is given by:I = (bd³)/12

Therefore,I = (80 x 150³)/12

I = 3,375,000 mm⁴

y, the distance from the neutral axis to the extreme fiber, is given by:y = h/2

Therefore,y = 150/2y = 75 mm

Now, we can use the formula for Zp.

Zp=I / y

Therefore,Zp = 3,375,000/75

Zp = 45,000 mm³

Now that we have the plastic section modulus, we can use the formula for the plastic moment to calculate the value of Mp.

Mp= Fy * Zp

Therefore,Mp = 200 * 45,000Mp = 9,000,000 N.mm

Mp = 9,000 N.m

Therefore, the plastic moment of the beam section shown in the given figure when it is made of an elastoplastic material whose yield strength is 200 MPa is 9,000 N.m.

So, the correct answer is : a 938 N−m

Answers

FMECA stands for Failure Modes, Effects, and Criticality Analysis. It is a powerful analytical method utilized to identify potential system failures and prioritize mitigating actions. The following are the typical lessons one can learn from design FMECA:

Mitigation measures: It is essential to develop a comprehensive list of mitigation measures that can be used to eliminate or minimize the impact of failures identified during FMECA. These measures may include redesign, redundancy, backup systems, and preventative maintenance plans.

Redesign: The results of the FMECA can identify specific areas of the design that need to be redesigned. These redesign efforts may lead to the incorporation of new materials, modifications to the manufacturing process, or adjustments to the design specifications.

Testing: FMECA can assist in identifying critical test cases that must be carried out to evaluate and verify the reliability of the design. The testing must be designed to reflect the potential failure modes and modes of operation.

Criticality: FMECA can assist in determining the criticality of different components of the system. Criticality is a measure of how important a specific component is to the overall performance of the system. Critical components must be prioritized during design, testing, and maintenance.

One solution: A potential solution to improve the reliability of a system could be to redesign the system to incorporate redundant systems. Redundancy involves incorporating backup systems that can take over the function of the primary system in case of failure. For example, an airplane engine may have multiple redundant systems to ensure that the plane can continue to fly even if one of the engines fails.

The load of an industrial concern is 400 kVA at a power factor of 75 lagging. An additional motor load of 100 kW is needed. Find the new kilovolt-ampere load if the motor to be added is an 80 power factor (leading) synchronous motor.

Answers

To solve this problem, we need to consider the power factor and calculate the reactive power (VAR) component for both the existing load and the motor to be added.Given:Existing load: 400 kVA at a power factor of 0.75 lagging.

Additional motor load: 100 kW at a power factor of 0.80 leading.Step 1: Calculate the real power (kW) and reactive power (kVAR) for the existing load.Real Power (kW) = Apparent Power (kVA) x Power FactorkW = 400 kVA x 0.75 = 300 kWReactive Power (kVAR) = sqrt((Apparent Power (kVA))^2 - (Real Power (kW))^2)kVAR = sqrt((400 kVA)^2 - (300 kW)^2) ≈ 200 kVAR (approximately)

Step 2: Calculate the reactive power (kVAR) for the additional motor load.

Given: Motor Power (kW) = 100 kW and Power Factor = 0.80 leading.Reactive Power (kVAR) = sqrt((Apparent Power (kVA))^2 - (Real Power (kW))^2)Since we know the power factor (leading), we can rearrange the formula:kVAR = sqrt((Real Power (kW))^2 - (Apparent Power (kVA))^2)kVAR = sqrt((100 kW)^2 - (Apparent Power (kVA))^2)Step 3: Calculate the new kilovolt-ampere load.The new kilovolt-ampere load will be the sum of the existing load and the additional motor load.New kilovolt-ampere load = Existing Load (kVA) + Additional Motor Load (kVA)New kilovolt-ampere load = (Real Power (kW) + Reactive Power (kVAR)) / Power Factor (leading)Now, let's calculate the values:

Existing Load (kVA) = 400 kVA (given)

Additional Motor Load (kVA) = (100 kW + Reactive Power (kVAR)) / Power Factor (leading)

Substituting the known values into the equation:

Additional Motor Load (kVA) = (100 kW + sqrt((100 kW)^2 - (Apparent Power (kVA))^2)) / 0.80

We need to solve this equation to find the value of Apparent Power (kVA).

Answers

The total entropy change is 4641.7 J/K.

Given: Mass of ice, m = 1.8 kg

Initial temperature of ice, T1 = 212 K

Final temperature of steam, T2 = 404 K

Pressure, P = constant

Now, first we need to calculate the entropy change of ice from 212 K to reach its freezing point.

Entropy change (ΔS) = mc [ln(T2/T1)]

Where m = mass of substance, c = specific heat capacity, and T2/T1 is temperature ratio.

Here, c = specific heat capacity of ice,

ΔT = T2 - T1 = 273 - 212 = 61 K

ΔS = (1.8 × 2.632) × ln(273/212)

ΔS = 3.15 J/K

The entropy change when ice changes to water at freezing point is given by the formula:

Entropy change (ΔS) = mL

Where L = Latent heat of fusion of ice = 334.7 kJ/kg

ΔS = 1.8 × 334.7

ΔS = 602.46 J/K

Similarly, we can calculate the entropy change of water from freezing point to boiling point, which is given by the formula:

Entropy change (ΔS) = mc [ln(T2/T1)]

Here, c = specific heat capacity of water and ΔT = T2 - T1 = 100 - 0 = 100 KΔS = (1.8 × 4.184) × ln(373/273)

ΔS = 17.02 J/K

The entropy change when water changes to steam at the boiling point is given by the formula:

Entropy change (ΔS) = mL

Where L = Latent heat of vaporization of water at boiling point = 2232 kJ/kg

ΔS = 1.8 × 2232

ΔS = 4017.6 J/K

Finally, we need to calculate the entropy change of steam from boiling point to 404 K. Here, c = specific heat capacity of water vapour,

ΔT = T2 - T1 = 404 - 373 = 31 K

Entropy change (ΔS) = mc [ln(T2/T1)]

ΔS = (1.8 × 2.632) × ln(404/373)

ΔS = 1.47 J/K

Total entropy change,

ΔStotal = ΔS1 + ΔS2 + ΔS3 + ΔS4 + ΔS5

ΔStotal = 3.15 + 602.46 + 17.02 + 4017.6 + 1.47 = 4641.7 J/

 ∣y∣=x is a continuous function at x = 0, and x = 2. Given function is, ∣y∣ = x.Here, we can say that given function is a piecewise function. When x is greater than or equal to 0, then |y| is equal to x, and when x is less than 0, then |y| is equal to -x.

That is why we need to check the continuity of the function from both sides of 0, i.e. at x=0- and x=0+.Now let us check whether the function is continuous at x = 0- or not:∣y∣ = -x here, x < 0, and y < 0As x approaches zero from the left, then ∣y∣ = -x approaches 0 from the left.Now let us check whether the function is continuous at x = 0+ or not:∣y∣ = x here, x > 0, and y > 0As x approaches zero from the right, then ∣y∣ = x approaches 0 from the right.Here we can see that the left and right limits of the function are equal to each other at x = 0. Thus, we can say that ∣y∣=x is a continuous function at x = 0. Now let us check for x = 2

.Let us check whether the function is continuous at x = 2- or not:∣y∣ = -x here, x < 2, and y < 0As x approaches 2 from the left, then ∣y∣ = -x approaches -2.Now let us check whether the function is continuous at x = 2+ or not:∣y∣ = x here, x > 2, and y > 0As x approaches 2 from the right, then ∣y∣ = x approaches 2.Here we can see that the left and right limits of the function are not equal to each other at x = 2.

Design a full return (fall) polynomial cam that satisfies the following boundary conditions (B.C): At θ = 0°, y = h, y' = 0, y" = 0 At θ= β, y = 0, y' = 0,y" = 0

Answers

To design a full return polynomial cam satisfying the given boundary conditions, we can use a quintic polynomial equation for the cam profile.

A polynomial cam profile can be represented by a polynomial equation. In this case, we need to design a full return or fall cam, which means the follower should return to its original position after completing a full rotation. The given boundary conditions provide information about the follower's position, velocity, and acceleration at two specific angles (θ = 0° and θ = β).

To satisfy these boundary conditions, we can use a quintic polynomial equation, which is a polynomial of degree five. A quintic polynomial can provide enough flexibility to match the given position, velocity, and acceleration requirements at the two specified angles. By solving the equations based on the boundary conditions, we can determine the coefficients of the quintic polynomial.

The quintic polynomial equation will have the form:

y(θ) = a₀ + a₁θ + a₂θ² + a₃θ³ + a₄θ⁴ + a₅θ⁵

where y(θ) represents the displacement of the follower as a function of the angle θ, and a₀, a₁, a₂, a₃, a₄, and a₅ are the coefficients of the polynomial.

By substituting the values of y, y', and y" at the two boundary angles (θ = 0° and θ = β) into the equation, we can obtain a system of equations. Solving this system of equations will allow us to determine the specific values of the coefficients a₀, a₁, a₂, a₃, a₄, and a₅.

This quintic polynomial equation will give us the desired cam profile that satisfies the given boundary conditions, ensuring that the follower returns to its original position after a complete rotation.
