The billboard sign shown weighs 4000 lb and is supported on a 15" circular hollow steel tube with 3/8" thickness. The sign will be built in west Mobile and is subjected to wind forces with maximum wind speed of 160 mph. The hollow steel tube has a maximum compressive/tensile strength of 50 Ksi and a maximum shear strength of 10 Ksi. Determine if the hollow steel tube has enough axial and shear strength to support loads applied to the sign....
