Redo Problem 6, but for the football goal post shown in Figure 4.22 in Chapter 4. Apply a uniform pressure of 40 psi on the crossbar and the uprights (this simulates gusting winds pushing on them). Fix the bottom face of the post where it meets the ground. What is the factor of safety? Is the model safe? Problem 6 Use the finite element method to check the strength of the brace drill handle Use a force of 200 N (~45 lb; 1 lb = 4.4482 N) at the drill bottom face. The load applies compression on the drill. Think of it as the environment pushing on the drill. Fix the top round face of the drill for the B.C. Use Alloy Steel for material. What is the factor of safety? Is the model safe?
