A concentrated load $P=4kN$ acts on a cantilever at an angle of $15,$ as shown. The beam is constructed of a $2024-$T$4$ aluminum alloy having a yield strength ${}_{yp}=290$MPa,$L=1\mathrm{.}5m,t=20mm,c=60mm,$ and $b=80mm.$ Determine $(a)$ the maximum stress $($in MPa$)$ in the beam and $($b$)$ whether it would be expected to yield under these conditions $($answer yes or no$).$ Also report $($c$)$ the angle of the neutral axis $($in deg$).$ Neglect the effect of shear in bending and assume that the load acts through the shear center. The centroid of the section is located $27\mathrm{.}14$ mm from the far left of the section. Take $I_y=15\mathrm{.}11{10}^{-7}{m}^4$ and $I_x=8\mathrm{.}93{10}^{-7}{m}^4.$
