Assume that the material is aluminum $($e$.$g$.,E=10\mathrm{.}3{10}^6).$

What is the maximum stress at the point A if $t1=0\mathrm{.}500"$ and $t2={0\mathrm{.}505}^{\text{'}\text{'}}?$ Assume the thinnest section of the parts are $0\mathrm{.}500"{2\mathrm{.}0}^{\text{'}\text{'}}$ and that the fasteners are $2"$ apart.
