The flywheel of a punching machine has a weight of 650 lb and a radius of gyration

Question:

The flywheel of a punching machine has a weight of 650 lb and a radius of gyration of 30 in. Each punching operation requires 1800 ft·lb of work.

(a) Knowing that the speed of the flywheel is 300 rpm just before a punching, determine the speed immediately after the punching.

(b) If a constant 15 lb·ft couple is applied to the shaft of the flywheel, determine the number of revolutions executed before the speed is again 300 rpm.
