Question: 

A single plate clutch, effective on both sides, is required to transmit 25 kW at
3000 rpm. Determine the outer and inner radii of frictional surface, if the
co-efficient of friction is 0.255 the ratio of radii is 1.25 and the maximum
pressure is not to exceed 0.1 N/mm 2 . Also determine the axial thrust to be
provided by springs. Assume the theory of uniform wear.
