3-50 with the following modifications:

Change the z-coordinate of point A from +6 ft to +8 ft

### Problem Statement

3-50. Determine the force in each cable if \( F = 500 \, \text{lb} \).

3-51. Determine the greatest force \( F \) that can be applied to the ring if each cable can support a maximum force of 800 lb.

### Diagram Explanation

The diagram illustrates a three-dimensional setup where a ring at point A is connected to three cables, leading to points B, C, and D on the ground plane. The positioning is defined as follows:

- **Point A** is located at the top of the diagram, suspended in the air.
- **Point B** is located 2 ft along the x-axis and 3 ft along the y-axis from the origin.
- **Point C** is located 3 ft along the x-axis and 1 ft along the y-axis.
- **Point D** is located 5 ft along the x-axis (3 ft + 2 ft) and 1 ft along the y-axis.

The height from the plane to point A, along the z-axis, is 6 ft. The cables connect the ring at A to points B, C, and D, forming a three-dimensional structure.

### Objective

The goal is to calculate:

1. The force in each cable when the ring is subjected to a force of 500 lb (Problem 3-50).
2. The maximum allowable force \( F \) that can be applied to the ring without any cable exceeding 800 lb of tension (Problem 3-51).

### Assessment

To solve these problems, the vector relationships and equilibrium equations will be used to determine the tensile forces in each cable.
