Q. To maintain a rotor at a uniform angular speed of $200\,rad\,s^{-1}$ an engine needs to transmit a torque of $180\,Nm$. The power of the engine required is (Assume the efficiency of the engine as 100%).

System of Particles and Rotational Motion

Solution:

Using power P = $\tau \, \omega$ , we get P = 180 $\times$ 200 = 36000 W
