EM $302$ Fall $2024$ Homework $8$

A wood post $150mm150mm$ cross section is side braced by two aluminum plates

$($on opposing sides$)$ each $6$ mm thick by $150$ mm wide. Determine the stress in each

material and the downward displacement of plate B$.$ Use $E_w=10$GPa and $E_{31}=70$GPa.

Also determine the aluminum thickness after loading if Poisson's ratio is $0\mathrm{.}333$ for the

aluminum.
