if the limit state for a column in compression is member buckling, describe the four ways that the capacity of a column can be increased.

Answers

Answer 1

Buckling will occur in thin structural members that are compressed and loaded axially. A relatively thin compression part, such as a column, could deflect laterally and fail via bending as opposed to failing by direct compression.

Compressing a plastic ruler will show you the behavior. Compression members are frequently employed as bridge piers, chords or webs in trusses, columns in building structures, and braces in framed constructions. The member length and end support circumstances have a significant impact on a steel compression member's maximum strength. When data is saved, compression, a column-level action, shrink the amount of data. Compression reduces the quantity of data read from storage and saves storage space. This decreases the amount of disk I/O, which enhances query performance.

A4 pole 500V shunt motor takes 7A on no load the no load speed of the motor if it takes 122A at full load armature resistance is 0.20 contact drop/brush is 1V ,armature reaction weakness the field by 40% on full load find the full load speed of the motor​

Answers

To find the full load speed of the motor, we can use the following formula:

Full load speed = (No load speed x (1 - (Armature current / Full load current) x (Armature resistance / (Total resistance - Armature resistance))))

Where:

No load speed is the speed of the motor at no loadArmature current is the current flowing through the armature at full loadFull load current is the current flowing through the motor at full loadArmature resistance is the resistance of the armatureTotal resistance is the total resistance of the motor, including armature resistance and field resistanceFirst, we need to find the total resistance of the motor:Total resistance = armature resistance + field resistance

Given that armature resistance is 0.20 Ohm, and the armature reaction weakens the field by 40% on full load, the field resistance is:

Field resistance = armature resistance x (1 + (40/100)) = 0.2 x 1.4 = 0.28 Ohm

Therefore, the total resistance is:

Total resistance = armature resistance + field resistance = 0.20 + 0.28 = 0.48 Ohm

No load speed of the motor is given as N0.

Now, we can plug in the values into the formula and get:

Full load speed = (N0 x (1 - (122 / 122 + 7) x (0.20 / (0.48 - 0.20))))

Given that the contact drop/brush is 1V and is neglected in the calculation.

We can now calculate the full load speed of the motor, which is the final answer.

specifications on a job require a fill using borrow soil to be compacted to 100% of its standard proctor maximum dry density. tests indicate that this maximum is 124 pcf when dry. the soil now has 12% moisture. the borrow material has a void ratio of 0.60 and a solid specific gravity of 2.65. what is the minimum volume of borrow soil required per 1 ft3 of fill volume?

Answers

For every 1 ft3 of fill volume, 1.14 ft3 of borrow soil is required.

To find the minimum volume of borrow soil required per 1 ft3 of fill volume, we need to find the wet density of the soil and compare it to the maximum dry density.

First, calculate the wet unit weight of the soil using the following formula:

wet unit weight = (dry unit weight x (1 + moisture content)) / (1 + void ratio x moisture content)

where,

dry unit weight = dry density / 62.4 (as dry density is in pcf and unit weight is in pcf)

Using the provided information:

Dry density = 124 pcf

Moisture content = 12%

Void ratio = 0.60

Solid specific gravity = 2.65

We can calculate the dry unit weight:

dry unit weight = 124 / 62.4 = 1.98

And the wet unit weight:

wet unit weight = (1.98 x (1 + 0.12)) / (1 + 0.60 x 0.12) = 2.25

And the wet density:

wet density = wet unit weight x 62.4 = 2.25 x 62.4 = 141.4 pcf

The minimum volume of borrow soil required per 1 ft3 of fill volume is 141.4/124 = 1.14.

In order to write the solution set of a homogeneous system of linear equations in parametric vector form, we can use the method of Gaussian elimination.

Gauss-Jordan elimination to find the reduced row-echelon form of the matrix representing the system. For example, in Exercise 5, we can write the augmented matrix of the system as follows:

[  1   3    1  0]

−4 −9   2 0

[0  −3 −6 0]

Applying Gaussian elimination, we can use row operations to transform the matrix into reduced row-echelon form:

[1  0  −2   0]

0  1    3    0

[0  0   0   0]

From this form, we can see that the system has an infinite number of solutions, represented by the parameterized vector. So the solution set can be written in parametric vector.

In Exercise 6, we can write the augmented matrix of the system as follows:

Applying Gaussian elimination, we can use row operations to transform the matrix into reduced row-echelon form. From this form, we can see that the system has a unique solution, represented by the vector:

So the solution set is the single vector (8 -2 - 3).

Presently, to switch 212°F steam over completely to 400°F steam, the expected intensity is ;

10 × .47 × 188 = 883.6 BTU

( The particular intensity on the off chance that steam is .47, Δt = 188°F )

Presently absolute intensity is, 883.6 BTU +9700 BTU + 1800 BTU + 110.77 BTU + 1440 BTU = 13934 BTU

Expected ability to change over it inside 20 min. or then again 1200 sec is,

13934/1200 = 11.61 BTUH.

We can now say that, assuming 10 pounds of ice begins at ten degrees and is changed to steam at 400 degrees in a short time, 11.61 BTUH is required.

butter is being turned by rotating cylinder of diameter 6 inches and height 24 inches centered within a 8 inch diameter tube (assume no interactions at the top or bottom of the cylinder - also note that these are diameters be careful with your calculations). mid process the power required to turn the mechanism at 2400 rpm is 168.4 w. what are the dynamic and kinematic viscosities (in cp and cst) of the butter at this point? assume no-slip conditions with a linear velocity profile. use 1.03 kg/l as the density of the butter at this state. later on the dynamic viscosity of the liquid doubles. how fast is the cylinder turning, if the system is operating under the same power conditions? (careful, rotational rate shows up in your calculation twice)

Answers

The first step is to calculate the flow rate (Q) and the shear rate (γ) at the conditions described in the problem.

For a cylinder rotating within a tube, the flow rate can be calculated using the following formula:

Q = π/4 * (D_cylinder^2 - D_tube^2) * H * v

where D_cylinder is the diameter of the cylinder (6 inches), D_tube is the diameter of the tube (8 inches), H is the height of the cylinder (24 inches), and v is the linear velocity at the wall of the tube (calculated below).

The linear velocity at the wall of the tube can be calculated using the following formula:

v = ω * r

where ω is the angular velocity of the cylinder (calculated below) and r is the radial distance from the center of the cylinder to the wall of the tube (4 inches).

The angular velocity of the cylinder can be calculated using the following formula:

ω = 2 * π * n / 60

where n is the rotational rate of the cylinder in revolutions per minute (2400 RPM).

Substituting the values into the above formulas, we have:

v = ω * r = (2 * π * 2400 / 60) * 4 = 80 * π

Q = π/4 * (6^2 - 8^2) * 24 * (80 * π) = 3136 * π cubic inches/s

The shear rate at the wall can be calculated using the following formula:

γ = 2 * v / D_cylinder = 2 * (80 * π) / 6 = 160 * π / 3

Next, we can use the following formula to calculate the dynamic viscosity (μ) at the conditions described in the problem:

P = μ * Q * γ / (2 * r)

where P is the power required to turn the mechanism (168.4 W).

Substituting the values into the formula, we have:

168.4 = μ * (3136 * π) * (160 * π / 3) / (2 * 4)

μ = 168.4 / (3136 * π * 160 * π / 3 / 8) = 1.03 Pa.s = 1.03 * 10^-3 N.s/m^2

The dynamic viscosity in centipoise (cP) can be calculated as follows:

μ (cP) = μ (Pa.s) * 10^3

μ (cP) = 1.03 * 10^-3 * 10^3 = 1.03 cP

The kinematic viscosity (ν) can be calculated using the following formula:

ν = μ / ρ

where ρ is the density of the butter (1.03 kg/l).

Substituting the values into the formula, we have:

ν (cSt) = μ (Pa.s) / ρ (kg/m^3) * 10^6

ν (cSt) = 1.03 * 10^-3 / (1.03 * 10^3) * 10^6 = 1.00 cSt

Later on, when the dynamic viscosity of the liquid doubles, the new dynamic viscosity (μ_new) is 2 * 1.03 Pa.s = 2.06 Pa.s.

Similar to Problem 2, launchControl System Designer, with G(s)=1/s2, andC(s)=Kd(s+Kp/Kd), using an arbitrary value for Kp/Kd,for example 1.

Answers

In the launchControl System Designer, the transfer function G(s) is defined as 1/s2 and the controller transfer function C(s) is defined as Kd(s+Kp/Kd).

Kp/Kd is an arbitrary value, and for example you can use a value of 1. This means that the controller transfer function is Kd(s+1). This configuration will allow the system designer to determine the optimal value for the proportional and derivative gain, Kp and Kd, for the system.

This configuration will provide the system designer with the ability to fine-tune the proportional and derivative gains, Kp and Kd, to achieve the desired performance and desired stability. The proportional gain, Kp, determines the system's response to a step input and determines how quickly the system will respond to a disturbance.

A 0.796-mH inductor produces an inductor reactance of 50 ohms at 10 kHz what value of capacitance will be needed to produce a resonant circuit at this frequency

Answers

The value of capacitance will be needed to produce a resonant circuit at this frequency is 79.6.

What is meant by capacitance?A material substance or device's capacity to store electric charge is known as its capacitance. It is determined by calculating the ratio between those two variables and measuring the change in charge in response to an alteration in electric potential. Depending on how much separated electric charge can be stored on it for each unit change in electrical potential, an electric conductor or collection of conductors has a property known as capacitance.Associated electrical energy storage is also implied by capacitance. As an illustration, if a capacitor with a capacitance of 3 farads is connected to a 5-volt battery, each conducting plate would have a charge of q = CV or q = (3 farads)x(5 volts) = 15 Coulombs of charge.

The reaction effluent goes to a condenser from which two streams emergers a liquid product stream containing essentially all of the methanol formed in the reactor, and a gas stream containing all of the CO, H2 leaving the reactor.

What a methanol synthesis loop with a stoichiometric feed?

A methanol synthesis loop with a stoichiometric feed of CO and H2 is to be designed for 95% overall conversion of CO. All the methanol formed leaves in the product stream.

Not more than 2% of the CO and 0.5% of the H2 emerging form the reactor is to leave in the product stream- the remainder is recycled.
