Afriction clutch is used to rotate a machine from a shaft rotating at a uniform speed of 250 r. p.m. the disc-type clutch has both of its sides effective with a friction coefficient of 0.3. the outer and the inner diameters of the friction plate are 200 mm and 120 mm respectively. the intensity of pressure is not to be more than 100 kn/m², calculate i. the power transmitted by this clutch based on the theory of uniform wear, ii. the intensity of pressure if the condition of uniform pressure is considered, and iii. the ratio of power transmitted with uniform wear to that with uniform pressure.
