**Problem 8.46**

**Instructions:**
Draw the influence lines for the forces in the members identified with an "×" in the figure. The moving load is transmitted to the bottom chord of the truss.

**Diagram Explanation:**

- The truss is a symmetrical structure with three triangular panels.
- Points A, B, C, and D are the supports of the truss on the ground level.
- Points E and F are at the top vertices of the triangle.
- The truss has a span of 9 meters, divided into three equal panels of 3 meters each.
- The height from the top chord (points E and F) to the bottom chord (points B and C) is 4 meters.
- Nodes at the joints include E, F, and along the bottom chord at each support.
- Members marked with an "×" show locations where the influence lines need to be drawn to analyze the forces acting on them when a moving load is applied.

**Objective:**
To understand how the forces in these specific members change as a moving load is applied across the structure. The analysis helps determine the maximum and minimum forces experienced by those members, which is crucial for the design and safety evaluation of the truss.
