The secondary winding resistance of an EI ignition coil indicates 1.5 ohms. Technician A says the coil should be replaced. Technician B says the coil winding is shorted. Who is correct?
Technician B is more likely to be correct as a secondary winding resistance of 1.5 ohms is lower than the typical range for an EI ignition coil, which is between 6 to 12 ohms.
This could be an indication of a short circuit in the coil winding. A short circuit occurs when the insulation between the coil windings breaks down, causing an electrical connection between the windings.
This can lead to a decrease in the coil's output voltage and may prevent the spark plugs from firing. Technician A's suggestion to replace the coil is also valid, as a faulty coil can cause a range of ignition problems,
but it does not necessarily address the root cause of the issue. It is recommended to further diagnose the ignition system to determine the exact cause of the problem before replacing any parts.

2. FurnictureCo, a furniture manufacturer, uses 20,000 square feet of plywood per month. Its trucking company charges FurnictureCo $400 per shipment, independent of the quantity purchased. The manufacturer offers an all unit quantity discount with a price of $1 per square foot for all orders under 20,000 square feet, $0.98 per square foot for orders between 20,000 and 40,000 square feet, and $0.96 per square foot for orders larger than 40,000 square feet. FurnictureCo incurs a holding cost of 20%. a. What is the optimal lot size for FurnictureCo? b. What is the annual cost for such a policy? c. What is the cycle inventory of plywood at FurnictureCo? d. How does it compare to the cycle inventory without the all unit quantity discount if all orders were $0.96 per square foot? Can you please provide answers for A,B,C AND D?
Compared to the all-unit quantity discount policy, no discount policy with a flat price of $ 0.96 is more economical and hence better.
How to solveAnnual demand, D = 20000*12 = 240,000 sqft
Fixed order cost, S = $ 400
Considering the unit cost, C = $ 1
Holding cost, H = 1*20% = $ 0.2
EOQ = sqrt(2DS/H)
= sqrt(2*240000*400/0.2)
= 30,984 sq ft
This is greater than 20,000 and less than 40,000 sq ft. Therefore, the applicable price for this quantity is $ 0.98
For C = $ 0.98, holding cost, H = 0.98*20% = $ 0.196
Revised EOQ = sqrt(2*240000*400/0.196) = 31,298 sq ft
Total annual cost of EOQ policy = Plywood purchase cost + Holding cost + Ordering cost
= D*C + H*Q/2 + S*D/Q
= 240000*0.98 + 0.196*31298/2 + 400*240000/31298
= $ 241,334.5
Now consider the next level of price, C = $ 0.96
Holding cost, H = 0.96*20% = $ 0.192
EOQ = sqrt(2*240000*400/0.192)
= 31633 sqft
This quantity is not feasible for this price, because it requires a minimum order of 40000 sqft.
Therefore, Q = 40,000
Total annual cost = 240000*0.96 + 0.192*40000/2 + 400*240000/40000
= $ 236,640
Total annual cost is lowest for order quantity of 40,000 sq ft.
1) Optimal lot size = 40,000 sq ft.
2) Annual cost of this policy = $ 236,640
3) Cycle inventory of plywood at Prefab = Q/2 = 40000/2 = 20,000 sq ft
4) If the manufacturer sells all plywood at $ 0.96, then
Holding cost, H = 0.96*20% = $ 0.192
EOQ = sqrt(2*240000*400/0.192)
= 31633 sqft
Total annual cost = 240000*0.96 + 0.192*31633/2 + 400*240000/31633
= $ 236,471.6
Difference in total annual cost = 236640 - 236471.6 = $ 168.4
Compared to the all-unit quantity discount policy, no discount policy with a flat price of $ 0.96 is more economical and hence better.

copper can be elongated by 3 mm when pulled in tension with a stress of 564 mpa. considering an elastic deformation, what is the original length of the copper piece (the young modulus of copper is 110 gpa) in these conditions?
In this question, we are asked to calculate the original length of a copper piece that can be elongated by 3 mm when pulled in tension with a stress of 564 MPa.
To solve this problem, we need to use the equation for the elastic deformation of a material, which relates the stress (σ), strain (ε), and Young's modulus (E) of the material. The equation is as follows:
σ = Eε
where σ is the stress, ε is the strain, and E is the Young's modulus.
We can rearrange this equation to solve for the strain:
ε = σ/E
We know the stress (564 MPa) and the Young's modulus of copper (110 GPa), so we can substitute these values into the equation to find the strain:
ε = 564 MPa / 110 GPa = 0.00513
This means that the copper piece has elongated by 0.513% of its original length (since strain is defined as the change in length divided by the original length).
We are also given that the elongation is 3 mm. So we can set up an equation to solve for the original length (L):
L + 3 mm = (1 + ε)L
where the (1 + ε) factor represents the total elongation as a percentage of the original length.
We can simplify this equation by dividing both sides by (1 + ε):
L = (3 mm) / (1 + ε)
L = (3 mm) / 1.00513
L = 2.9845 mm
Therefore, the original length of the copper piece is approximately 2.9845 mm.

in a 5 mm diameter vessel, what flow rate of a fluid with viscosity of 0.006 ns/m2, causes a wall shear stress of 0.84 n/m2? would the corresponding flow be laminar or turbulent?
To calculate the flow rate of the fluid, we can use the equation for wall shear stress:
τ = (4 * μ * Q) / (π * D)
Where τ is the wall shear stress, μ is the dynamic viscosity of the fluid, Q is the flow rate, and D is the diameter of the vessel.
Plugging in the values given, we get:
0.84 n/m2 = (4 * 0.006 ns/m2 * Q) / (π * 5 mm)
Simplifying this equation, we can solve for Q:
Q = (π * 5 mm * 0.84 n/m2) / (4 * 0.006 ns/m2)
Q ≈ 22.1 ml/s
To determine whether the corresponding flow is laminar or turbulent, we can use the Reynolds number:
Re = (ρ * v * D) / μ
Where ρ is the density of the fluid, v is the velocity of the fluid, and D and μ are as previously defined.
If the Reynolds number is less than 2300, the flow is laminar, and if it is greater than 4000, the flow is turbulent. In between these values, the flow is transitional.
Plugging in the values given, we get:
Re = (1000 kg/m3 * 0.0221 m/s * 0.005 m) / 0.006 ns/m2
Re ≈ 18.4
Since the Reynolds number is less than 2300, the flow in this vessel would be laminar.

What function does a steam trap perform?
A steam trap is a device used in steam systems to discharge condensate and non-condensable gases while preventing the escape of live steam. It works by automatically opening to discharge the condensate and then closing again to prevent the escape of steam.
The primary function of a steam trap is to remove condensate, which is the liquid water that forms when steam condenses as it cools. If condensate is not removed from the steam system, it can lead to water hammer, which is a sudden pressure surge that can damage pipes, valves, and other system components. Additionally, if condensate is allowed to accumulate in a steam system, it can reduce the efficiency of the system and decrease the amount of heat transferred to the process or equipment being heated.
Steam traps also help to prevent the loss of live steam, which is steam that has not yet condensed. Live steam is valuable because it contains heat energy, and its loss can lead to decreased efficiency and increased energy costs. By preventing the escape of live steam, steam traps help to conserve energy and reduce operating costs.

Mass of Betelgeuse = 32 × 10^30 kg
Volume = 5.24 × 10^44 m³
The average density = 6.1 × 10^(-14) kg/m³
How to solve for the massGiven that Betelgeuse has 16 times the mass of our Sun, and the Sun's mass is 2 × 10^30 kg, we can find the mass of Betelgeuse by multiplying the Sun's mass by 16:
Mass of Betelgeuse = 16 × (2 × 10^30 kg)
Mass of Betelgeuse = 32 × 10^30 kg
Radius = 500 million km × (1,000,000 m/km)
Radius = 500 × 10^6 km × 1,000,000 m/km
Radius = 500 × 10^6 × 10^6 m
Radius = 5 × 10^8 × 10^6 m
Radius = 5 × 10^14 m
To find the volume of Betelgeuse, we can use the formula for the volume of a sphere:
Volume = (4/3) × π × radius³
Volume = (4/3) × π × (5 × 10^14 m)³
Volume ≈ 5.24 × 10^44 m³
