Question

  A ceiling fan having moment of inertia 2kg -m^2 attains its maximum frequency of 60 rpm in 2 (pi) seconds.calculate its power.

Solve it ASAP :(​

Answer 1

Answer:

Given, l=2kg−m2,ω0=6060×2πrad/s

ω0 and t=60s

The torque required to stop the wheel's rotation is

τ=lα=l(tω0−ω)

τ=60×602×2π×60=15πN−m
