please solve the problem shown in the picture Problem $1$

Consider a simple truss consisting of three pin$-$ended bars connected to a common suspended joint.

All bars have the same cross$-$sectional area $\backslash ($ A$=300\backslash$mathrm$\{$mm$2\}\backslash ),$ and the same material properties $\backslash (\backslash$mathrm$\{$E$\}=1506\backslash$mathrm$\{$~Pa$\}\backslash )$

The vertical Load $\backslash ($ W$=50\backslash$mathrm$\{$kN$\}\backslash ),$ applied at the suspended joint, increases in magnitude. determine the evolution of load to total collaps
