QUESTION: 8

The torque transmitting capacity of a friction clutch can be increased by following methods except

Solution:

Concept: The torque transmitting capacity of friction clutches is given by

T = μ W Rm

Now the torque transmitting capacity can be increased by

  • Increasing μ (coefficient of friction)
  • Increasing W (pressure on plate)
  • Increasing Rm (mean radius)
