For the crane hook shown in Figure P11-16, determine the largest displacement and the maximum von Mises stress and where this value is located on the hook. Use AISI 4130 steel with yield strength of 66.7 ksi, modulus of elasticity of 30 × 103 ksi, and Poisson's ratio of 0.3. The total load of 22,500 lbf is applied over 15 nodes located on the bottom inside face to simulate a lifting force. The underside of the top of the circular portion of the hook is fixed from vertical translation. All dimensions are in inches?
