Question
**Problem Description:**

The light right-angle boom, which supports a 400-kg cylinder, is supported by three cables and a ball-and-socket joint at point O attached to the vertical x-y surface. Determine the reactions at point O and the cable tensions.

**Diagram Explanation:**

The diagram shows a three-dimensional setup of a right-angle boom. Key components and measurements are as follows:

- **Boom and Connectors:**
  - The boom extends from point A to point B, with a vertical segment and a horizontal segment.
  - A cylinder weighing 400 kg is suspended from point B.
  
- **Dimensions:**
  - From point A to point B, the horizontal length is 0.70 m along the z-axis.
  - From point B to the location directly beneath the cylinder, the vertical drop is 0.70 m along the y-axis.
  
- **Cables:**
  - Cable AC runs from point A to point C on the vertical wall.
  - Cable BD runs from point B to point D on the wall.
  - Cable BE runs from point B to point E on the wall.

- **Wall Attachment Points:**
  - Point C is located 1.00 m along the y-axis and 1.30 m above the origin O.
  - Point D is located 1.40 m along the x-axis and 1.30 m above origin O.
  - Point E is located 2.25 m along the x-axis and level with origin O.
  
- **Origin Point:**
  - Point O is a ball-and-socket joint located at the intersection of the x and y axes on the wall.

**Output Requirements:**

Calculate the following:
- Reactions at point O in three directions: \( O_x \), \( O_y \), \( O_z \).
- Tensions in the cables: \( T_{AC} \), \( T_{BD} \), \( T_{BE} \).

These values are necessary to determine how the forces distribute across the system to maintain equilibrium.
