A sign on the roadside of highway was supported by a 40 ft high pole, as shown in the figure. The sign has dimensions 6 ft by 3 ft and weighs 500 lb. The maximum wind pressure against the sign was calculated 150 lb/ft² when category 5 hurricane hits. Your job is design the pole and write a technical report about your decisions based on the calculations. Use all what you have learned in class and/or computer tools to do this project. You may consider all or most of the issues mentioned below:
e) Determine the stresses acting on a stress element at point A, which is on the outer surface of the pole at the "front" of the pole. Determine the principal stresses at point A. f) Determine the max deflection of the pole (maybe draw the deflection curve if possible). g) According to your design, what is the safety factor against of yielding failure? (if your dimension is too small and design failed, explain how are you going to do next) h) Check for buckling possibility of the pole. i) Discuss any other issues of your pole design you think they are important. j) Write your conclusion and comments to this design.
