Failure of Ductile Materials Under Static Loading Problem 5.1: Problem Given Assumptions Determine the safety factors for the bracket rod shown in Figure 5-9 based on both the distortion-energy theory and the maximum shear theory and compare them. The material is 2024-T4 aluminum with a yield strength of 47 000 psi. The rod length /= 6 in and arm a = 8 in. The rod outside diameter d=1.5 in. Load F = 1000 lb. The load is static and the assembly is at room temperature. Consider shear due to transverse loading as well as other stresses. wall B arm rod Figure 5.9
