The 5-ft concrete post is reinforced with six steel bars, each with a -in. diameter. Knowing that Es = 29 x 106 psi and Ec= 3.6 106 psi, determine the normal stresses in the steel and in the concrete when a 160-kip axial centric force is applied to the post. 5 ft 10 in. 10 in. The normal stresses are as follows: 05=- ksi ksi
