**Problem 5-5: Cable Support System**

The diagram illustrates a cable support system subjected to a loading. The objective is to determine the magnitude of the horizontal force \( P \) needed to maintain equilibrium when the horizontal distance \( x \) is 6 feet.

**Diagram Explanation:**

- A cable is shown supporting a force, with points labeled \( A \), \( B \), \( C \), and \( D \). 
- The cable starts at point \( A \), moves vertically to point \( B \), and runs horizontally to point \( C \). From point \( C \), it then extends diagonally to point \( D \), where a 400 lb horizontal force is applied.
- The vertical distance from \( A \) to \( B \) is 5 ft.
- The horizontal distance from \( A \) to \( D \) is 2 ft.
- The horizontal distance from \( C \) to the wall (point \( B \)) is variable \( x \), specified to be 6 ft in this problem.
- The vertical distance from \( B \) to \( C \) is 8 ft.
- The diagram includes a static force applied at point \( D \).

**Objective:**

To determine the magnitude of the horizontal force \( P \) necessary to keep the system in equilibrium with \( x = 6 \) ft. 

This requires analyzing the static equilibrium of the system, considering forces and distances provided in this setup.
