A power press makes steel pressings. The energy required foreach pressing is 5000J with each pressing taking 1s. The time takento remove the pressing and get the material ready for the nextpressing is 4s.If the press is operated by an electric motor whichruns continuously with a flywheel used to supply the extra torquerequired for the pressing. Determine the power of the motor that isrequired, the energy that has to be supplied by the flywheel andthe moment of inertia of the flywheel if it’s speed is not to dropby more than 30 RPM from a speed of 600 RPM.
