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 `omega = 200 rad s^(-1), tau = 180 Nm`
`therefore` Power, `P= tau omega = 180 xx 200 = 36,000 W = 36 kW`.
