1. In the beginning of engagement of a centrifugal clutch,

2.

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.

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

4. 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

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

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

7. In case of multi-plate clutch if n1 is number of disks on driving shaft and n2 is the number of disks on driven shaft, then the number of pairs of contacting surfaces is given by

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

9. The friction material of the clutch should have

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