As shown in the figure, the solid shaft with a pulley weighing
20kg on the shaft transmits 10 horsepower at 1150 rpm by a
horizontally wound flat belt. Find the diameter of the axis by
shear strain energy breakage theory. However, the outer diameter of
the pulley is 75mm, the ratio of the belt pulling force is T1/T2 =
1.25, the tensile strength of the shaft is 66kg/mm^2, the yield
strength is 55kg/mm^2, the safety ratio 1.8, the fatigue stress
concentration factor is 1.5 and the surface of the shaft is
machined.
