1.	A flywheel of mass 400 kg and one metre radius makes 600 rev/minute. Assuming its mass to be concentrated at the rim, calculate the angular velocity, M.I. and energy of the flywheel.
Answer» Solution :`omega = 2pin = 2pi XX 10 = 62.8 rad/s K.E. (1//2) lomega^(2) , omega = V//r, m_(1)gh =7v^(2) , v= 23.66 MS^(-1), omega =v//r = 118.3 rad s^(-1)`
