5 52 A constant net torque equal to 20 N m is exerted on a pivoted wheel for 8 sec during which time the angular velocity of the wheel increases from zero to 100 re min The external torque is then removed and the wheel is brought to rest by friction in its bearings in 70 sec Compute a the moment of inertia of the wheel about the rotation axis b the friction torque c the total no of revolutions made by the wheel in the 70 sec time interval Ans 15 3 kg m 2 29 N m 58 3 revl
