General Considerations in Machine Design
Following are the general considerations in designing a machine component :
1. Type of load and stresses caused by the load.
Difference between Flywheel and Governor

cycle.
Multi – Plate clutch consists of a number of clutch plates instead of only one clutch plate like in
the Single plate clutch.
Friction surface also increased because of a number of clutch plates. Because of number of
friction surfaces, the capacity of the clutch to transmit torque is also increased.
The plates are alternately fitted to the engine crankshaft and gearbox shaft. They are firmly
pressed by strong coil springs and assembled in a drum type casing.
