Required information A solid round bar with a diameter of 2.97 in has a groove cut to a diameter of 2.676 in, with a radius of 0.15 in. The bar is not rotating. The bar is loaded with a repeated bending load that causes the bending moment at the groove to fluctuate between 0 and 25,000 lbf·in. The bar is hot-rolled AISI 1095, but the groove has been machined. Determine the factor of safety for fatigue based on infinite life...
