1. The friction moment in a clutch with uniform wear as compared to friction moment with uniform pressure is

2. The commonly used angle between leather or asbestos friction lining surface and axis of cone clutch for a cone clutch is

3. The friction material of the clutch should have

4. The friction radius for new clutch compared to worn out clutch will be

5.

In case of single plate worn out clutches and brakes, the friction radius is equal to

    Where, ‘D’ and ‘d’ are outer and inner diameters of friction lining respectively.

6. The torque transmitted by single plate clutch, working on uniform wear criterion, is given by,    Where, µ = coefficient of friction, P = axial force required to hold the friction surfaces together, Rmin = mean radius of friction surfaces

7. In the running condition, the net force acting on the drum of centrifugal clutch is equal to

8. In case of cone clutch, a relatively small axial force can transmit a given torque, if the semi-cone angle is
