25 KN Using the method that has been covered, find the displacement of the node 2 if E1 = 100 GPa and A1=10-6 m² and E2= 200 GPa and A2=2x10 6 m². N2 5 cm 2 30° N3 N1, Note: The stiffness matrix of individual elements should be first written, then the equilibrium equations at each node should be written, expanded in terms of nodal displacement, and used to perform the assembly of the global stiffness matrix of the problem. Then, the appropriate boundary conditions should be applied and the nodal displacement vector should be found. Every step should be shown; missing any step would result in point deduction even if the final answer is correct
