The $4\mathrm{.}5-$ft concrete post is reinforced with six steel bars, each with a$.1\frac{1}{8}-$in$.$ diameter. Knolwing that $E_S=29{10}^{6}p$ pi and $E_C=4\mathrm{.}2{10}^6,$ determine the normal stresses in the steel and in the concrete when a $348-$kip axial centric force $P$ is applied to the post.

The normal stress in the steel is $]$ksi$.$

The normal stress in the is concrete ksi
