Answer:
in dia rod
Explanation:
Given;
Maximum tensile stress = 20,000 psi
Applied tensile load = 35,000 lb
Now,
the area of the steel rod required =
or
the area of the steel rod required =
or
the area of the steel rod required = 1.75 in²
Also, Area of rod =
where, d is the diameter of the rod
1.75 in² =
or
d = 1.49 in
So we can use in dia rod
Answer:
The correct answer is option C. pneumatic power transfer
Explanation:
Pneumatic power transfer is mostly used in food processing industry. The reason is because this pneumatic system usually consists of just air in the form of gas, which means that they will not face any poisonous leakages in the food production houses.
These systems rely heavily on the constant supply of compressed air which is then used to transmit and control the energy.
The power factor of the circuit is 0.7071
<h3>What is Power factor?</h3>
Power factor (PF) is the ratio of working power, measured in kilowatts (kW), to apparent power, measured in kilovolt amperes (kVA). Apparent power, also known as demand, is the measure of the amount of power used to run machinery and equipment during a certain period. It is found by multiplying (kVA = V x A). The result is expressed as kVA units.
Power factor is expressed as the cosine of the phase angle.
The phase angle is given as 45°
Therefore the power factor in the circuit is cos45° = 0.7071
