An automobile engine develops 100 kW when rotating at a speed of `1800 rev//min`. What torque does it deliver ?

A

`350` N-m

B

`440` N-m

C

`531` N-m

D

`628` N-m

Text Solution

Verified by Experts

The correct Answer is:
C
Power (P) = `100kW,f=(1800)/(60)=30` rad/s
`omega=60 pi` rad/s
Power `(P)=vec(tau).vec(omega)`
implies `tau=(100xx10^(3))/(60pi)=531 N-m`
