ABSTRACT
The finite displacements can be integrated to show that the work done on the particle is equal to the change in its kinetic energy. The internal energy of the system is composed of both potential and kinetic energy. During run down the internal energy determined by the kinetic energy stored in the flywheel and the thermal energy stored in the system. When heat is transferred into a system the temperature of the system always increase provided no transformation of phase, such as from solid to liquid, occurs. The change in the internal energy corresponding to this increase in temperature is equal to the change in the thermal energy of the system. A crank-slider mechanism is driven by the flywheel and the tool used to punch out the laminations is rigidly fixed to the slider. The tool makes contact with the strip before the slider approaches its lower extreme, or Bottom Dead Centre (BDC), position.
