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? (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.
