A swivel C bracket shown in Figure P11–23 is mounted to a ceiling of a building and has a speaker (not shown) of 20 lbf hanging from each mounting hole. The mounting bracket is made of A 36 steel with a modulus of elasticity of 29 × 10⁶ psi, Poisson’s ratio of 0.29, and yield strength of 36,000 psi. Determine the maximum von Mises stress and deflection in the bracket. (This problem is compliments of Tyler Austin and Kyle Jones.)
