Question

A cylindrical bar of ductile cast iron is subjected to reversed and rotating-bending tests, test results (i.e., S-N behavior) are shown in Animated Figure 9.27. If the bar diameter is 10.3 mm, determine the maximum cyclic load that may be applied to ensure that fatigue failure will not occur. Assume a factor of safety of 2.18 and that the distance between load-bearing points is 52.4 mm.
