Problem $02\mathrm{.}050-$ Thermal stresses in a composite column

The concrete post psi and $\{$:${}_C=5\mathrm{.}5\frac{{10}^{-6}}{}F)$ is reinforced with six steel bars, each of $\frac{7}{8}-$in$.$ diameter psi

and ${}_S=6\mathrm{.}5\frac{{10}^{-6}}{}F.$ Determine the normal stresses induced in the steel and in the concrete by a temperature rise of $60F.$

The normal stress in the steel is

ksi.

The normal stress in the concrete is

psi.
