A foot step bearing has a shaft 140 mm diameter is counter bored with a hole of 70 mm diameter al the end. The shaft rotates at 120 rpm. Calculate
(a) The axial load
(b) Frictional Torque
(c) Heat generated al the bearing if the allowable bearing pressure is 0.8 MN/m² by using Uniform wear theory.
Take coefficient of friction, mu = 0.045
