$3\mathrm{.}3)$ A compression member within a bridge truss is constructed using a wide$-$flange

steel section as shown below. The cross$-$sectional area is $8\mathrm{.}5i{n}^2$ and the applied axial

load is $80k,$ calculate the normal and shear stresses be subjected to all faces of stress

elements positioned in the web of the beam, oriented at $($a$)$ theta$=0,($b$)$ theta$=30,$ and

$($c$)$ theta$=45.$ Present the stresses for each scenario on a sketch showing the oriented

stress element.
