InterviewSolution

1.	To maintain a rotor at a uniform angular speed of 200 rad s^(-1), an engine needs to transmit a torque of 180 Nm. What is the power required by the engine? Assume that the engine is 100% efficient.
Answer» <P> Solution :Here `omega = 200 rad s^(-1), tau= 180 NM` `THEREFORE` Power, `P= tau omega = 180 xx 200 = 36,000 W = 36 kW`.
