A punching press is required to punch 30 mm dia holes in a plate of 20 mm thick at the rate of 20 holes/minute. It requires 6 N-m of energy per mm2 of sheared area.

If punching takes place in 1/10 of a second and rpm of the flywheel varies from 160 to 140, determine the weight of the flywheel having radius of gyration K = 1m
