2. A machine shaft turning at 600 rpm is supported on bearings 20" apart. Twenty HP is supplied to the shaft through a 20" pulley located 10" to the right of the right bearing. The power is transmitted from the shaft through an 8" spur gear located at the middle of the two bearing. The pulley weighs 300 lb to provide some flywheel effect. The forces acting on the pulley and the gear are given in the diagram. The shaft material selected has an ultimate strength of 70,000 psi and a yield stress of 46,000 psi, determine: Reactions at the bearings b. Bending moment diagrams in the horizontal and vertical directions a. с. The necessary diameter in accordance with the ASME Code using Kb =1.5 and Kt = 1.5. Pulley Mt 525 lb Gear 191 lb Mt
