) A solid round bar with diameter of 2-in has a groove cut to a diameter of 1.8-in, with a groove radius of 0.1-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 25000 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 (use the ASME elliptical criteria) and the factor of safety for yielding. ** Note: For a non-rotating, circular cross-section, an effective diameter is used to determine the size based Marin factor. Please refer to equations 6-22 through 6-25 in your book

Final answer:

The factor of safety for fatigue and yielding can be determined using the ASME elliptical criteria and comparing stress to the yield strength of the material.

Step-by-step explanation:

The factor of safety for fatigue based on infinite life can be determined using the ASME elliptical criteria. The ASME elliptical criteria use equations 6-22 through 6-25 to calculate the factor of safety. The factor of safety for yielding can be calculated by comparing the maximum stress in the bar to the yield strength of the material.
