Solved: A beryllium-copper metal flat belt with Sf 5 56.67
Chapter 17, Problem 17-15(choose chapter or problem)
A beryllium-copper metal flat belt with \(S_f = 56.67\) kpsi is to transmit 5 hp at 1125 rev/min with a life goal of \(10^6\) 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.
