The $$5?\mathrm{ft}$$ concrete post is reinforced with six steel bars, each with a $$\frac{7}{8}$$-in. diameter. Knowing that $$E_S=29\times 10^6\mathrm{psi}$$ and $$E_C=3.6\times 10^6$$ psi, determine the normal stresses in the steel and in the concrete when a 230-kip axial centric force is applied to the post. The normal stresses are as follows: $$\begin{array}{ll}{?}_S=?& \mathrm{ksi}\\ {?}_C=?& \mathrm{ksi}\end{array}$$
