Chapter 5, Problem 24P
Figure P5−24shows a hydraulic cylinder that pushes a heavy tool during the outward stroke, placing a compressive load of 400 lb in the piston rod. During the return stroke, the rod pulls on the tool with a force of 1500 lb. Compute the resulting design factor for the 0.60-in-diameter rod when subjected to this pattern of forces for many cycles. The material is SAE 4130 WQT 1300 steel. If the resulting design factor is much different from 4.0, determine the size of the rod that would produce
