All necessary equations must be embedded within the related problems. Please solve correctly. 2. ( \( \mathbf{2 5} \) pts) Consider the system of linear elastic springs shown below. Assume that only horizontal displacements are allowed. (a) Construct the element connectivity table. (b) Write down the element stiffness matrices. (c) Write down the global stiffness matrix. (d) Assemble the element equations to obtain the force-displacement relations for the whole system. (e) Apply boundary conditions, then construct the reduced global equilibrium equation in matrix form in terms of spring stiffness, unknown nodal displacements, and forces. Note-1: You are free to choose the minimum potential energy approach or the direct stiffness approach. Note-2: Do not renumber the nodes.
