Questions
A wheel having moment of inertia of 2 kg-m2 about its vertical axis, rotates at the rate of 60 rpm about this axis. The torque which can stop the wheel's rotation in one minute would be
detailed solution
Correct option is C
Given that I=2kg−m2,ω0=(60/60)×2πrad/sec ω=0 and t=60sec Now, torque λ=Iα=Iω0−ωt∴ λ=22π−060=π15N−mSimilar Questions
