6. Determine the force in member HI, FI, and EF of the truss.
The image depicts a truss structure with several labeled joints and forces acting on it. The truss is a simple planar type with horizontal and diagonal members.

### Text Description:
- **Text:** "Consider the truss shown in . Suppose that \( F = 9 \text{ kN} \)."

### Diagram Details:
- **Joints:** The truss has several joints labeled as A, B, C, D, E, F, G, H, I, J, K, and L.
- **Forces Applied:**
  - At joint B, there is a downward force of 4 kN.
  - At joint C, there is a downward force of 5 kN.
  - An unspecified force, \( F \), is applied at joint D.
  - At joint E, a downward force of 6 kN is present.
- **Distances:**
  - The horizontal distance between each consecutive vertical member (A, B, C, D, E, F, G) is 2 meters.
  - The height from the base level at point A or B to the upper chord (at K) is 3 meters.
- **Support:**
  - There appears to be a pinned support at joint A and a roller support at joint G.

This truss system is typically analyzed to find reactions at the supports and forces in the truss members using methods such as the method of joints or sections, considering the internal forces and equilibrium of the structure.
