Question

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%). (A) 360 W (B) 9000 W (C) 36000 W (D) 96000 W

Using power P = τ ω , we get P = 180 × 200 = 36000 W

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

360 W

9000 W

36000 W

96000 W

Using power P = $τ ω$ , we get P = 180 $\times$ 200 = 36000 W
