1. For the structure shown in FIGURE 1 below, each element has a cross sectional area, A = 0.001 m, and modules of elasticity, E = 109 Pa. The structure is discretized into five elements. The 10 kN force is parallel to element "e" and applied as shown in Figure below. Element (a) is 4 m long. a. b. C. d. Hinge Roller 000 (d) 90% 3 (e) FIGURE 1 Model each bar as finite element. (b) 60 Calculate the displacement at all nodes 10 kN Establish the element-nodes and the cosines direction table. Develop the force - stiffness-displacement matrix of each element.
