The Electro-Poly Corporation is the world’s leading manufacturer
of slip rings. A
slip ring is an electrical coupling device that allows current to
pass through a spinning or rotating connection—such as a gun turret
on a ship, aircraft, or tank. The
company recently received a $750,000 order for various quantities
of three types of
slip rings. Each slip ring requires a certain amount of time to
wire and harness. The
following table summarizes the requirements for the three models of...

6) What are the minimum expected values of starting torque, pull
up torque and breakdown torque for a 60 Hz, eight pole, 100 HP,
NEMA A design B induction motor which runs at 870 RPM when
operating at rated load?
Q1: How to draw equivalent induction machine circuit?
Q2: What is the rotor resistance including slip. Why is it R2/s
and R2 (s)/(1-s)
Q3: how to find power of the output given torque and speed?
Q4: what are the formulas for Pin?
Explain the significance of, and the mechanisms behind, slip in
metals. What is a slip system? In a pure material, what governs the
ease of slip? Why are some crystal structures easier to slip than
others? Why are ceramic materials normally very resistant to
slip?
Does the resistance torque change as leg position is changed?
Explain, based on the average scores for perceived exertion, which
leg position is easiest to perform and which is hardest. Why are
there differences in perceived exertion for the different leg
positions?
A coin and a ring have the same mass and radius. Starting from
rest and the same height, they roll down the same incline. In other
words, they both start with the same gravitational potential
energy. Which one of the following statements is true about the
coin and ring when they reach the bottom of the incline?
A. The increase in the coin's total kinetic energy is less than
the increase in the ring's total kinetic energy.
B. The increase...
