A CST structure is subjected to a compressive traction acting on the top

edge and a concentrated force F at the top of the right edge, as shown in the

figure below. Use the following values: E$=30\backslash$times $10^(6)\backslash$psi $,$

u $=0\mathrm{.}3,\backslash$iota $=100$in$,$

L$=10$in$,$H$=5$in$,$s$\_(2)=10$ksi, and F$=750$kip.

$($a$)$ Compute all the nodal displacements. Clearly identify their respective

units.

$($b$)$ Compute the element stress components $\backslash$sigma $\_($x$),\backslash$sigma $\_($y$),$ and $\backslash$tau $\_($xy$).$ Clearly iden$-$

tify their respective units.

$($c$)$ Compute the element planar principal stresses $\backslash$sigma $\_(1^(\text{'}))$ and $\backslash$sigma $\_(2^(\text{'})).$ Clearly

identify their respective units.

$($d$)$ Compute the element Von Mises and Tresca effective stresses. Clearly

identify their respective units.
