Assembly of springs. Use FEA to find the displacements of nodes 3, 5, and 6 and the nodal forces on elements 3 and 4. Indicate if these elements are under tension or compression. The spring constants and the applied load are: k = 30 lb/in k = 50 lb/in k3 = 120 lb/in k4 = 200 lb/in k5 = 125 lb/in F = 100 lb 1 21 2 1 (2) 3 (3) M W 4 5 4 (5) 6 F
