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)= 100 kW, `f= (1800)/(60)= 30` rad/s
`omega= 60pi` rad/s
Power (P) = `vec(tau). vec(omega)`
`rArr tau= (100 xx 10^(3))/(60 pi) = 531N-m`
