The bars system shown in Figure below consists of two steel bars and one aluminum bar. The bars are fixed to the wall at nodes 1 and 4, and are connected to each other at nodes 2 and 3. An axial load, P = 104 N is applied at node 2. The bars specifications are shown in table below. Bar type Steel bars Aluminum bar 3 m steel + 2 4 m P Aluminum cross section area, A (m²) 0.0024 0.0006 3 3 m steel Modules of Elasticity, E (N/m²) 200 x 10⁹ 70 x 10⁹ Develop the stiffness matrix of each element. Assemble the global stiffness matrix of the bars system. Determine the displacements at each joint point at the walls and between the bars.
