The two profiles shown in the figure below represent the cross$-$

sections of two columns designed to resist axial compressive

stresses. The dimensions in the figure are in inches. If the ultimate

strength of the material of both columns is $21$ ksi $($kilo$-$pounds per

square inch$),$ and a factor of safety of $2\mathrm{.}5$ is recommended, calculate

the maximum compressive load $P$ in kip $($kilo$-$pounds$)$ that can be

safely applied on each column.
