Question
The diagram illustrates a 3D mechanical system with two horizontal beams connected by a joint at point B and supported by various cables. The coordinate axes are labeled as x, y, and z.

Components and Measurements:
- A beam extends from point D to point C along the x-axis.
- The x-axis shows points C and D with a distance of 11 feet between them (4 ft from C to B, 3 ft from B to A, and 4 ft from A to D).
- The z-axis is 4 ft away from the support wall for point D.
- The y-axis is positioned 3 ft above the ground level, aligned vertically with points A and E.
- Point C is experiencing a downward force of 300 lb.
  
Support and Cable Structure:
- Cable segments are represented by blue lines connecting various points.
- The cable connects E to A, A to D, and F to C.
- The distance from point E to the support wall is 6 ft along the y-axis.

This setup provides an understanding of the spatial relationship between support points, cable lengths, and the applied force, critical for analyzing the tension in cables and stability of the beam system.
