Question
The flywheel (I = mk² ) shown has a radius of 20 in. a weight of 250 lbs, and a radius of
gyration of 15 in. A 30-lb block A is attached to a wire that is wrapped around the
flywheel, and the system is released from rest. Neglecting the effect of friction,
determine (a) the acceleration of block A and (b) the speed of block A after it has moved
5 ft. Use Newton's second law.(Answers: a = 5.66 ft/s v¼ = 7.52 ft/s |)
