$1/16 \mathrm{in}.=0.0625 \mathrm{in}.$

An aluminum rod $\left(2\right)$ is to be connected to a brass post $\left(1\right)$. When the two axial members were installed, however, it was discovered that there was a $1/16-\mathrm{in}.$ gap between flange $\mathrm{B}$ and the brass post.

If bolts are inserted through the flange at $\mathrm{B}$ and tightened until the gap is closed, how much stress will be induced in each of the axial members?

The brass post $\left(1\right)$ has a cross-sectional area of ${\mathrm{A}}_1=0.60 {\text{in.}}^2$ and an elastic modulus of ${\mathrm{E}}_1=16,000 \mathrm{ksi}.$

The aluminum rod $\left(2\right)$ has properties of ${\mathrm{A}}_2=0.20 {\text{in.}}^2$ and ${\mathrm{E}}_2=10,000 \mathrm{ksi}.$
