Question: A beryllium-copper metal flat belt with Sf = 56.67 kpsi is to transmit 5 hp at 1125 rev/min with a life goal of 106 belt

A beryllium-copper metal flat belt with Sf = 56.67 kpsi is to transmit 5 hp at 1125 rev/min with a life goal of 106 belt passes between two shafts 20 in apart whose centerlines are in a horizontal plane. The coefficient of friction between belt and pulley is 0.32. The conditions are such that a service factor of 1.25 and a design factor of 1.1 are appropriate. The driven shaft rotates at one-third the motor-pulley speed. Specify your belt, pulley sizes, and initial tension at installation.
