A truss is loaded as shown in Fig$\mathrm{.}9\mathrm{.}15$Using the $[$Python gausspivot$]$equations$,$ solve for the $10$ unknowns, $AB,BC,AD,BD,CD,DE,CE,A_x,A_y,$ and $E_y.$

$A_x+AD=0,-24-CD-(\frac{4}{5})CE=0$

$A_y+AB=0,-AD+DE-(\frac{3}{5})BD=0$

$74+BC+(\frac{3}{5})BD=0,CD+(\frac{4}{5})BD=0$

$-AB-(\frac{4}{5})BD=0,-DE-(\frac{3}{5})CE=0$

$-BC+(\frac{3}{5})CE=0,E_y+(\frac{4}{5})CE=0$
