The frame below resists the lateral forces where P $=6$ kips. The frame is

made of a composite material has a compressive failure stress, $\backslash$sigma fail,comp $=$

$500$ psi and a tensile failure stress, $\backslash$sigma fail,tens $=900$ psi. If the required factor

of safety is $1\mathrm{.}5,$ what is the required cross sectional area of members AC$,$

DC$,$ BD and CE$?$
