Verify the global stiffness matrix of Example 2.3 using (a) dir... | Filo

For the spring assemblage shown in Figure 2-13, obtain (a) the global stiffness matrix, (b) the displacements of nodes 2-4, (c) the global nodal forces, and (d) the local element forces. Node 1 is fixed while node 5 is given a fixed, known displacement δ = 20.0 mm. The spring constants are all equal to k = 200 kN/m.
