**Problem Statement:**

2. Frame ABCD is supported by a ball-and-socket joint at A and by three cables. For \( a = 150 \, \text{mm} \), determine the tension in each cable and the reaction at A.

---

**Diagram Description:**

The diagram shows a 3D coordinate system with the frame ABCD. The frame is supported at point A by a ball-and-socket joint, and at three additional points by cables (EG, CF, AH). 

- **Point A**: Located at the base of the frame.
- **Point B**: Located \( 300 \, \text{mm} \) along the positive x-axis from A.
- **Point C**: Located \( 140 \, \text{mm} \) vertically above B.
- **Point D**: Laterally positioned at \( a = 150 \, \text{mm} \) along the positive x-axis from C.
- **Points E, F, G** are positioned horizontally and vertically along the y and z axes from A.
  - **E to A**: \( 480 \, \text{mm} \) along the z-axis.
  - **F to A**: \( 200 \, \text{mm} \) vertically along the y-axis.
  - **G to C**: \( 140 \, \text{mm} \) vertically above C.

The force \( 350 \, \text{N} \) is acting downward at point H. 

Cables EG, CF, and AH are attached to stabilize the frame. 

The diagram illustrates the positions and dimensions necessary to calculate tensions in the cables and the reactions at joint A.
