Repeat problem 2 by changing node numbers; that is, node 3 is now node 1 , and node 1 is now node 3. Check if the results are the same as those of problem 2.

Data From Problem 2:

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$=1000N$ is applied at node 2. Use k⁽¹⁾$=2000N/mm$ and k⁽² $\mathrm{ \; =\; 3000}N/mm$.
