Note: The stiffness matrix of individual springs 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.
