Using the equilibrium and compatibility equation to solve:

Two cylindrical rods, $AC$ made of aluminum and $CD$ made of steel, are joined at $C$

and restrained by rigid supports at A and $D.$ It is given that $E_a=10\mathrm{.}4{10}^6,E_S=$

$29{10}^6$ psi, and $P=16$ kips.

Determine the reactions at A and $D.$

The reaction at $A$ is

kips.

The reaction at $D$ is

kips.
