3. (10 Points) A thin-wall (.100") 3.5" diameter steel post filled with concrete will safely support what axial load if limited to the working stress of 22,000 psi for steel and 9000 psi for concrete. Hint: calculate P for the steel and concrete separately and then sum the loads. You know all the math to solve this problem - applications of knowledge. -0.1000 3.5 A36 Steel F(22ksi) Concrete F(9ksi)
