For the truss shown above, $x1=5\mathrm{.}4m,x2=2\mathrm{.}1m,y1=3\mathrm{.}9m$ and $y2=y1(\frac{x2}{x1}).$

$($Figure is NOT to scale$).$ The bolded members $($AB and $BC)$ have a weight per unit length of $W=3k\frac{N}{m},$ and all other members have negligible weight. The magnitude of the applied forces are $P1=6kN$ and $P2=14kN.$

Solve for the force in members $AB,BD,$ and $,$ and $($:$F_{DE}$
