In the figure shown below; the wire support DE is made of steel, with yield stress $36$ksi.

The values of $L,P$ and a are given as follows:

$L=98in$

$P=32000lbs$

$a=47$ degrees

Determine the minimum allowable cross sectional area of member DE if the required factor of safety is $2\mathrm{.}8$ and the point $B$ is pinned.
