### Problem 2: Analysis of Truss Members **Objective:** In Figure 2, determine the force in members CD, CJ, and GJ and state if the members are in tension or compression. Also, determine the force in members CG and HG. #### Diagram Description: **Figure 2:** This figure illustrates a truss structure supporting various loads. The truss is composed of several members connected at joints labeled A, B, C, D, E, G, H, and J. - **Loads and Support:** - A 4 kN load is applied vertically downward at joint A. - A 6 kN load is applied vertically downward at joint H. - A 12 kN load is applied vertically downward at joint G. - A 9 kN load is applied vertically downward at joint J. - A 6 kN load is applied vertically downward at joint E. **Geometrical Layout:** - The base of the truss spans horizontally from A to E, with equal segments measuring 1.5 meters between each of the joints A-B, B-C, C-D, and D-E. - The vertical distances for the truss members are 1 meter between joint B-C and D-J, while the vertical distance is 2 meters between joints C-G and G-J. #### Task: For the calculation of forces in the specified members: - Use methods such as the joint method or section method to determine the forces. - Specify whether each member (CD, CJ, GJ, CG, and HG) is in tension (being pulled apart) or compression (being pushed together). #### Analysis Approach: - **Joint Method:** Resolve forces at each joint to find out the member forces. - **Section Method:** Cut through the truss and solve for unknown forces using equilibrium equations. This analysis is crucial for understanding the load-bearing and structural integrity of truss systems in engineering applications.
