Construct the mathematical FE equations $\{$F$\}=[$K$]\{$U$\}$ for this system and solve them using suitable software $($e$.$g$.$ Excel,. Matlab, etc.$).$ It is expected that your model will allow you to calculate the displacements and forces at each of the nodes $-$ these should be compared with the results from your FEA model. $2\mathrm{.}1$ Truss Frame

Figure $1$ shows a truss frame. The frame consists of nine elements. All the elements have the same material properties, and these are listed in Table $1.$
