A hand-driven grinding wheel is a uniform disk of 66 kg having a 53 cm radius. It consists of a handle of negligible mass 64 cm from the rotation axis. A compact load of 23 kg is joined to the handle when it is at the similar height as the horizontal rotation axis. Avoid the effects of the friction.
(i) Determine the initial angular acceleration of the wheel.
(ii) Determine the maximum angular velocity of the wheel.
