To maintain a rotor at a uniform angular...

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 of the engine required ?

Text Solution

Verified by Experts

Here, `a=200 rad s^(-1)`, Torque, T=180 N-m
Since, Power, P=Torque (T)x angular speed (w)
`=180xx200=36000` watt =36 KW.
