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 8.21. If the bar diameter is
8.52 mm, determine the maximum cyclic load that may be applied to
ensure that fatigue failure will not occur. Assume a factor of
safety of 2.21 and that the distance between loadbearing points is
55.3 mm.
