Q) A multiple clutch has three pairs of contact surfaces. The outer and inner radii of the contact surfaces are 100 mm and 50 mm respectively. The maximum axial spring force is limited to 1 kN. If the coefficient of fiction is 0.35, assuming uniform wear, find the power transmitted by the clutch at 1500 r.p.m.

A)It is required to use a multiplate clutch to transmit power of 24 kW at 1200 r.p.m. If the clutch has the following data: • The Outer and inner plate radii are 120 mm and 80 mm respectively. • Maximum axial pressure pmax=0.12 N/mm?. • Coefficient of friction=0.3. Find: 1. The axial load (W) required. 2. The number of effective pairs of contact surfaces (n).

The axial pressure on a single disc clutch (both sides of the disc is effective) is limited to 0.12 Mpa. This is designed for a vehicle with 13kW power at a speed of 700 rpm. Assume uniform wear conditions and a friction coefficient of 0.25. If the outer dimater of the disc is 1.25 times the internal diameter, determine the dimensions of the disc lining and the axial force exerted by the springs.
