Question: Calculate the displacement at node 2 and reaction forces at nodes 1 and 3 of the springs shown in the figure using two spring elements.

Calculate the displacement at node 2 and reaction forces at nodes 1 and 3 of the springs shown in the figure using two spring elements. A force $F=1000 \mathrm{~N}$ is applied at node 2 . Use $k^{(1)}=2000 \mathrm{~N} / \mathrm{mm}$ and $k^{(2)}=3000 \mathrm{~N} / \mathrm{mm}$.
