$[4]$ A beam for an aircraft is made from the l$-$section shown at right. It is made of $7075-16$ Al Die Forging, with $F_{tu}=75$ksi and $F_{ty}=65\mathrm{.}0$ksi. If $A=0\mathrm{.}93i{n}^2,y_{\text{b}\text{o}\text{r}}=1\mathrm{.}5$ in$.$ & $1=1\mathrm{.}6439$ int, determine the Ultimate Bending Moment of Rupture Ma and the Ulimate Bending Modulus of Rupture Fo using the cozzone Method.
