To maintain a rotor at a uniform angular speed of 200 rad.s^(-1), an engine needs to transmit a torque of 180 N. m . What is the power required by the engine? ( Note: uniform angular velocity in the absence of friction implies zero torque. In practice, applied torque is needed to counter frictional torque ) Assume that the engine is 100% efficient.
