$2)$ The $6-$member truss structure shown in the figure is subjected to the force $\backslash (\backslash$boldsymbol$\{$F$\}=\backslash$mathbf$\{25\}\backslash$mathrm$\{$kN$\}\backslash ).$ Determine the location and magnitude of horizontal and vertical nodal displacements $[$ mm $].$ Also, determine the location and magnitude of maximum element stress $[$MPa$].$ Assume all members have a cross section of $\backslash (250\backslash$mathrm$\{$~mm$\}^\{2\}\backslash )$ and are made of Steel $(\backslash ($ E$=207\backslash$mathrm$\{$GPa$\}\backslash )).$ Solve the problem by analytical method and then verify the results using a finite element program.
