Question
The flywheel of a small punch rotates at 300 rpm. It is known that 1,800 ft lb of work must be done each time a hole is punched. it is desired that the speed of the flywheel after one punching be not less that 90 percent of the original speed of 300 rpm.
A. Determine the required moment of inertia of the flywheel.
B. If a constant 25 lb ft couple is applied to the shaft at the flywheel, determine the number of revolutions which must occur between each punching, knowing that the initial velocity is to be 300 rpm at the start of each punching.
