Question

Input -Output Given: A multiple-disk dry clutch for an industrial application must transmit 6 hp at 200 rpm. Based on space limitations, inside and outside disk diameters have been set at 5 and 7 in., respectively. Materials are hardened steel and sintered bronze. Tests have indicated that design values of pmax - 225 psi and f = 0.2 are appropriate. Find: (a) For a safety factor of 2 with respect to clutch slippage, what total number of disks is needed? (b) Using this number of disks, what is the smallest clamping force that gives the desired torque? (c) Using this clamping force, what is the interface pressure at the inside and outside radii after "initial wear" has taken place? [Answers: (a) 3, (b) 3150 lb, (c) 200 and 143 psi]
