A solid round bar with diameter of 50.800 mm has a groove cut to a diameter of 45.720 mm, with a radius of 2.540 mm. 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 2825.000 N m. The bar is hot-rolled AISI 1095, but the groove has been machined. Determine the factor of safety for fatigue based on infinite life using the Goodman criterion, and the factor of safety for yielding.
