Problem $02\mathrm{.}052-$ Thermal stresses in a composite rod with ends restrained

A rod consisting of two cylindrical portions $AB$ and $BC$ is restrained at both ends. Portion

$AB$ is made of steel $(E_S=29{10}^6$ and ${}_S=6\mathrm{.}5\frac{{10}^{-6}}{}F)$ and portion $BC$ is made of

aluminum $(E_a=10\mathrm{.}4{10}^6$ and $\{$:${}_a=13\mathrm{.}3\frac{{10}^{-6}}{}F).$ The rod is initially unstressed

before a temperature rise of $72F.$

Problem $02\mathrm{.}052.$a $-$ Thermal stresses in a composite rod with ends restrained

Determine the normal stress induced in portions $AB$ and $BC$ due to the temperature rise.

The normal stress induced in portion $AB$ is

ksi.

The normal stress induced in portion $BC$ is

ksi.
