question

The flywheel of a cutting machine has a mass of 62.5 slugs and a radius of gyration of 3 ft. At the beginning of the cutting stroke it has a rotational speed of 120 rev\bulletmin^-1, and at the end a speed of 90 rev\bulletmin^-1. If it cuts in a 6-in. stroke, what is the average cutting force exerted?
