For the same truss in the previous question, and using the Method of Joints, the forces in members AE and AB are closest to which values? (Hint: On scratch paper, draw a free-body diagram at point A and use the component method to determine member force components, and then the member force resultants. Include in the FBD the reaction at A determined in the previous question)

Question
For the same truss in the previous question, and using the Method of Joints, the forces in members AE and AB are closest to which values? (Hint: On scratch paper, draw a free-body diagram at point A and use the component method to determine member force components, and then the member force resultants. Include in the FBD the reaction at A determined in the previous question.)

### Truss Diagram Explanation:

The truss diagram features a series of interconnected triangles pinned at joints A, B, C, D, E, F, and G. The load distribution and layout are as follows:

- **Span:** The total span of the truss is divided into sections—12 feet on each side from points A to B, B to C, and C to D.
- **Loads:** Vertical loads are applied at:
  - Point E: 2400 pounds
  - Point F: 4800 pounds
  - Point G: 4800 pounds
  - Symmetrical loads of 2400 pounds each at leftmost and rightmost points (unspecified location, presumably at E and symmetrical G).
- **Angles:** A 30-degree angle is indicated at the lower-left section of the truss between members at joint E.
- **Supports:** The truss is supported at points A and D.

This truss system requires analyzing the forces in specific members, particularly AE and AB, using the Method of Joints to determine internal member forces and reactions at supports.
