The centrifugal clutches are used in light duty vehicles and not in heavy duty vehicles.
Chain saws, lawnmowers, golf carts etc. never use centrifugal clutches.
In a centrifugal clutch, when the centrifugal force is slightly more than the spring force, shoe begins to move in a radially inward direction.
Centrifugal clutches are not recommended for IC engine applications.
A cone clutch transmits 24kW at 490rpm. The coefficient of friction is 0.2 and allowable intensity of pressure is 0.35N/mm . The semi cone angle is 12 . The outer diameter is fixed as 310mm.Assuming uniform wear theory; calculate force required to engage clutch.

A cone clutch with a small semi cone angle requires a relatively large force to engage and small force to disengage.
When semi vertical angle is greater than angle of static friction, clutch results in self-engagement.
