Amultiple disk clutch, steel on bronze, is to transmit 5 hp at 750 rpm. the inner radius of contact is 1.5 in and the outer radius of contact is 2.75 in. the clutch operates in oil with an expected coefficient of friction 0.10. (oil is used to give smoother engagement, better dissipation of heat, even though the capacity is reduced.) the average allowable pressure. is 50 psi, maximum. (how design pressures are used to provide for sufficient size to give yood heat dissipation capacity.) assuming uniform wear, determine the following: a) how many total dishes of sted and bronze are required? b) what axial force is required? c) what is the average pressure?

Adouble-strand no. 60 roller chain is used to transmit power between a 13-tooth driving sprocket rotating at 300 rev/min and a 52-tooth driven sprocket. a) what is the allowable horsepower of this drive? b) estimate the center-to-center distance if the chain length is 82 pitches. c) estimate the torque and bending force on the driving shaft by the chain if the actual horsepower transmitted is 30 percent less than the corrected (allowable) power.
