During the design of a friction clutch what are the considerations that should be made?

In order to design a friction clutch the following points must be kept in mind:

> The material for the contact surfaces must be carefully selected.

> For high speed devices to minimize the inertia load of the clutch, low weight moving parts must be selected.

> The contact of the friction surfaces must be maintained at all the times without the application of any external forces.

> Provisions for the facilitation of repairs must be there.

> In order to increase safety the projecting parts of a clutch must be covered.

> A provision to take up the wearing of the contact surfaces must be present.

> Heat dissipaters to take away the heat from the point of contacting surfaces must be there.
