• To investigate the behavior of flat clutch plates.
  • To investigate the Behavior of different clutch plates of different Materials.
  • Comparison of different methods of calculation.


  • The clutch plate set consists of 4 plates with the different dimensions.
  • Different type of surfaces for friction

Clutch plates are used to connect and disconnect driven part from the driving part temporarily. This apparatus demonstrates the concept of clutch friction using different types of clutch plates.

It consists of flat disc of leather against which a clutch plate is loaded. The clutch plate is secured by screws to the effort pulley. A torque is applied to the effort pulley by dead weight using two load cords. The main load on the effort pulley and thus the clutch plate is applied by a loading arm system via a thrust bearing.
