A riveting machine is driven by a 3.5 kW motor. The moment of inertia of the rotating parts of the machine is equivalent to 67.5 kg-m2 at the shaft on which the flywheel is mounted. At the commencement of an operation, the flywheel is making 240 r.p.m. If closing a rivet occupies 1 second and corresponds to an expenditure of 9 kN-m of energy, find the reduction of speed of the flywheel. What is the maximum rate at which rivets can be closed ?
