A lawn mower component experiences critical static stresses of sx = 45,000 psi, sy = 25,000 psi, and txy = 15,000 psi. The component is made of 4130 normalized steel that has an ultimate strength of 97,000 psi and a yield strength of 63,300 psi. Determine the factor of safety based on predicting failure by the maximum-normalstress theory, the maximum-shear-stress theory, and the distortion energy theory
