The 4.5-ft concrete post is reinforced with six steel
Chapter 2, Problem 2.35(choose chapter or problem)
The 4.5-ft concrete post is reinforced with six steel bars, each with a \(1 \frac{1}{8} \text {-in. }\) diameter. Knowing that \(E_{s}=29 \times 10^{6} \text { psi and } E_{c}=4.2 \times 10^{6}\), determine the normal stresses in the steel and in the concrete when a 350-kip axial centric force P is applied to the post.
