The concrete post $($Ec $=3\mathrm{.}6\backslash$times $106$ psi and $\backslash$alpha c $=5\mathrm{.}5\backslash$times $10-6/\backslash$deg F$)$ is reinforced with six steel bars, each of $78-$in$.$

diameter $($Es $=29\backslash$times $106$ psi and $\backslash$alpha s $=6\mathrm{.}5\backslash$times $10-6/\backslash$deg F$).$ Determine the normal stresses induced in the steel and in the concrete by a temperature rise of $60\backslash$deg F$.$
