Question
**Problem Statement:**

If the weight of the boom is negligible compared with the applied 49-kN load, determine the cable tensions \( T_1 \) and \( T_2 \) and the force acting at the ball joint at \( A \).

**Diagram Explanation:**

The diagram features a 3D coordinate system with axes labeled \( x \), \( y \), and \( z \). It represents a structure involving:

- A point \( A \) located at the intersection of the wall with coordinates on the \( y \)-axis.
- A boom extending horizontally from \( A \) with segments: 
  - \( AB \) with a length of 5 meters. 
  - \( BC \), forming a right-angled triangle with other segments.
- A 49-kN vertical load is applied downward at point \( B \).

Supporting cables are shown:

- Cable \( T_1 \) extends from point \( B \) (at \( z = 2 \) m and \( x = 1 \) m) to point \( C \) on the wall at (0, 3, 0).
- Cable \( T_2 \) extends from point \( B \) to point \( D \).

**Answer Section:**

- \( T_1 = \) ___ kN
- \( T_2 = \) ___ kN
- \( A = \) ___ kN
