Two steels are being considered for manufacture of as-forged connecting rods subjected to bending loads. One is a Cr-Mo-Ni alloy steel capable of being heat-treated to a tensile strength of 240 ksi. The other is a plain carbon steel with an attainable Sut of 105 ksi. Each rod is to have a size giving an equivalent diameter de of 1 in. Determine the endurance limit for each material. Is there any advantage to using the alloy steel for this fatigue application?
