What is the complex power S?
(A) (1.9 + j24) VA
(B) (16.4 + j21.1) VA
(C) (7,8 - j16.5) VA
(D) (21.1 + j16.4) VA​

Answers

Explanation:

Now we change into rectangular form

=40 cos (36.9°) +j 40 sin (36.9°) VA

=31.9+J24VA

Hence, correct option (31.9 +j 24) VA

A 13.2 KV circuit has a 10,000 kVA load with a 0.85 lagging power factor. How much capacitive reactive power (in KVAR) is needed to conect the P.F. to 0.97 lagging?
​

Answers

Explanation:

Solving for the capacitive reactive power, we have

Qc = 8,500 (tan(-cos (0.85)) - tan(-cos¹ (0.97)))

Qc = -3137.5261 = -3138 KVAR

a threaded rod has 11 threads per inch how many threads are there in 16 inches of the rod

Answers

The number of threads in 16 inches of the rod is 176 threads

Calculation and Parameters

Given that:

1 threaded rod= 11 threads per inch

Therefore, to find the number of threads in 16 inches of the rod,

We would have to multiply and this is given below:

16 * 11= 176 threads

This answer is gotten because a threaded rod has 11 threads per inch and when there are 16 inches of rod, to find the number of inches, you would have to multiply the values together.

tech a says that black exhaust indicates a very rich-running engine. tech b says that white exhaust can indicate coolant in the exhaust. who is correct?

Answers

Since tech A says that black exhaust indicates a very rich-running engine is false and since tech b says that white exhaust can indicate coolant in the exhaust, Tech B  is correct.

What does it mean when your exhaust pipe is black?

Black exhaust smoke is known to be one that can show up if the vehicle is said to be burning too much fuel.

Note that this situation could be as a result of  a clogged air filter, the malfunctioning of the fuel injection system, a blocked manifold, or other forms of issues.

Therefore, Since tech A says that black exhaust indicates a very rich-running engine is false and since tech b says that white exhaust can indicate coolant in the exhaust, Tech B  is correct.

A shaft of a circular cross section is supported by two housings at B and C. The shaft
is subjected to static loads: concentrated force N applied by gear D and an applied torque T. The yielding strength of the shaft is Sy, and the diameter of the shaft is d. For circular cross sections, | = nd*/64, J = md*/32. The length of the shaft is L. Transverse shear stress is ignored here.

1) Draw the bending moment diagram of the shaft. Specify the location of the weakest (most dangerous) cross section A on bending moment diagram.

2) Draw the weakest point(s) on cross section A.

3) Determine the von-Mises stress at the weakest point(s).

4) Determine the factor of safety n based on Distortion Energy Theory.

Answers

Answer:

1) The bending moment diagram of the shaft is shown in Figure 1. The weakest cross section A is located at the point where the bending moment is maximum.

2) The weakest point on cross section A is located at the point where the bending moment is maximum.

3) The von-Mises stress at the weakest point is given by:

σ = M/I

where M is the bending moment and I is the moment of inertia of the cross section.

4) The factor of safety n is given by:

n = Sy/σ

where Sy is the yield strength of the shaft and σ is the von-Mises stress at the weakest point.
