a. Obtain the global stiffness matrix K of the assemblage shown in Figure 1 by superimposing the stiffness matrices of the individual springs. Here k₁, k2, and k3 are the stiffnesses of the springs as shown. b. If nodes 1 and 2 are fixed and a force P acts on node 4 in the positive x direction, find an expression for the displacements of nodes 3 and 4. c. Determine the reaction forces at nodes 1 and 2. (Hint: Do this problem by writing the nodal equilibrium equations and then making use of the force/displacement relationships for each element. Then solve the problem by the direct stiffness method.) sig 3 Frünárnő 4 X
