Transcribed Image Text:**Problem Description:**
**Q.3)** An airplane wing is supported by a truss structure as shown below. Three vertical forces are applied at points \( C, D, \) and \( E \) along the upper surface of the wing. Use the Method of Sections to find the force in members \( BC, CG, \) and \( GF \). Indicate whether the member is in tension or compression.
**Diagram Explanation:**
1. **Truss Diagram:**
- A truss structure supports an airplane wing.
- Points \( A, B, C, D, E, F, G, H, \) and \( I \) are joints in the truss.
- Members connect these points, creating triangular and rectangular shapes.
2. **Dimensions:**
- Horizontal members: \( AB, BC, CD, DE \) each measured at 8 feet.
3. **Forces:**
- 2500 lb downward at point \( C \).
- 3000 lb downward at point \( D \).
- 1500 lb downward at point \( E \).
**Objective:**
- Analyze using the Method of Sections to calculate the forces in members \( BC, CG, \) and \( GF \).
- Determine if each member is under tension (being pulled apart) or compression (being pushed together).
