Solve Problem $2\mathrm{.}35(8$ points$)$

$2\mathrm{.}35$ The $5-$ft concrete post is reinforced with six steel bars, each with a $\frac{7}{8}-$in$.$ diameter. Knowing that $E_s=29{10}^6$ and $E_c=3\mathrm{.}6{10}^6,$ determine the normal stresses in the steel and in the concrete when a $200-$kip axial centric force is applied to the post.
