PLEASE ANSWER BY HAND IT ALLOWS ME TO UNDERSTAND THE PROBLEM SO MUCH BETTER. SOME ANSWERS ARE $($Vy $=+800)$ Problem $4\mathrm{.}3$: For the beam shown below, there are two applied forces on the free end; viewing the span view.

Use the same cross$-$section as in Problem $4\mathrm{.}2.$

$($a$)$ Find the magnitude of the largest bending stress at the wall & indicate whether it is tension or compression.

$($b$)$ Give the sign & magnitude of $M_y$&$M_z$ that you used in the flexure formula.

$($c$)$ Give the equation of the N$.$A$.$ & sketch it$.$

$($d$)$ Place an $*$ on both the span view & the cross$-$section view where the largest bending stress occurs.

$($e$)$ Find the magnitude of the largest shear stress.

$($f$)$ Give the sign & magnitude of $V_y$&$V_z$ that you used in the shear flow formula.

$($g$)$ Place an # on both the span view & the cross$-$section view where the largest shear stress occurs.

$($h$)$ If $F_u=70,000,F_y=58,000,F_{su}=37,000,E=10{10}^6$; will the beam fail?
