Q$5.$ The concrete post $(E_c=3\mathrm{.}6{10}^6$ psi and ${}_c=5\mathrm{.}5\frac{{10}^{-6}}{\frac{?}{?}}\frac{?}{?}$ degree $F)$ is reinforced with six steel bars, each of $\frac{7}{8}-$in diameter $(E_s=29{10}^6$ psi and ${}_s=6\mathrm{.}5\frac{{10}^{-6}}{\frac{?}{?}}\frac{?}{?}$ degree $F).$ Determine the normal stresses induced in the steel and in the concrete by a temperature rise of $65F.(10$ pts$)$
