1. (Problem 2.36 from the text book) The 5-ft high concrete post is reinforced with six steel bars, each with a 3 -in. diameter. Knowing that the Modulus of Steel, Es = 29 x 10° psi, and the Modulus of Concrete, Ec = 3.6 × 10° psi, determine the maximum centric force that can be applied if the allowable normal stress is 15 ksi in the steel and 1.6 ksi in the concrete. 5 ft 10 in. 10 in.
