Repeat problem 42 with an external force added to node 3, as shown in figure (c).

Data From Problem 42:

Repeat problem 41 for the new configuration with element 5 added, as shown in figure (b)

Data From Problem 41:

Use the finite element method to determine the nodal displacements in the plane truss shown in figure (a). The temperature of element 2 is \(200^{\circ} \mathrm{C}\) above the reference temperature, that is, \(\Delta T^{(2)}=200^{\circ} \mathrm{C}\). Compute the force in each element. Show that the force equilibrium is satisfied at node 3. Assume \(L=1 \mathrm{~m}, A E=10^{7} \mathrm{~N}, \alpha=5 \times 10^{-6} /{ }^{\circ} \mathrm{C}\).
