Beam Structures: For the $"$I$-$beam" subjected to F$-12$ kip, Compute Normal

Stresses at points A$,$ B$,$ C$,$ D and E$.$ Note: The Beam Parameters are given.

$A=9\mathrm{.}5i{n}^2$

$t=0\mathrm{.}5in.(uniform)$

$I_x=143\mathrm{.}3i{n}^4$

$I_y=10\mathrm{.}3i{n}^4$

Show Work $($Details of How Stresses in the Table were obtained$)$: MUST include stresses for each axial direction, x$,$y$,$z$,$ for each point.
