A single plate clutch, effective on both sides, is required to transmit 33.5 HP at 3000 r.p.m. Determine the outer and inner diameters of frictional surface if the coefficient of friction is 0.255, ratio of diameters is 1.25 and the maximum pressure is not to exceed 0.0l kgf/mm2. Also, determine the axial thrust to be provided by springs. Assume the theory of uniform wear.
