A truncated conical pivot bearing which supports an axial load of 20000N from a vertical shaft rotating at 180 rpm has a cone angle of 120°. Its larger diameter is 2.5 times its smaller diameter. The normal pressure on the bearing is not to exceed 36 N/cm. Determine the dimensions of the bearing. If the coefficient of friction is 0.05 for the bearing surface, find the power lost in overcoming the friction.

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.
