Question

To maintain a rotor at a uniform angular speed of 200 rad/s, an engine needs
to transmit a torque of 80 Nm. What is the power required by the engine?
Assume that the engine is 100 % efficient.

Answer 1

Answer:

In practice, applied torque is needed to counter frictional torque). Assume that the engine is 100 % efficient. Hence, the power required by the engine is 36 kW
