WebA machine has to carry out punching operation at the rate of 10 holes per minute. It does 6 kN-m of work per mm of the sheared area in cutting 25 mm diameter holes in 20 mm thick plates. A flywheel is fitted to the machine shaft which is driven by a constant torque. The fluctuation of speed is between 180 and 200 r.p.m. WebQuestion: A motor driving a punching machine exerts a constant torque of 675 Nm on the flywheel which rotates at an average speed of 120 rev/min. The punch operates 60 times per minute, the duration of the punch operation being 0.2s. It may be assumed that the punching effort is equivalent to a constant torque on the flywheel and that friction and … how many airports are in chicago
