**Title: Analyzing the Tension in Supporting Structures**

**Problem Statement:**
The pipe \( ACDE \) is supported by ball-and-socket joints at points \( A \) and \( E \), as well as by the wire \( DF \). Determine the tension in the wire when a 640-N load is applied at point \( B \) as illustrated.

**Diagram Explanation:**
The diagram presents a three-dimensional view of a pipe system supported at multiple points:

- **Pipe Structure:** The pipe segments \( ACDE \) are shown with connections at defined points \( A \), \( C \), \( D \), and \( E \).

- **Support Points:**
  - **Ball-and-Socket Joints:** Located at \( A \) and \( E \), these joints provide multi-directional support.
  - **Wire \( DF \):** The wire is connected between points \( D \) and \( F \).

- **Applied Load:**
  - A downward force of 640 N acts on point \( B \).

**Dimensions Provided:**
- The pipe is positioned such that:
  - \( AB = 490 \, \text{mm} \)
  - \( BC = 480 \, \text{mm} \)
  - \( CD = 240 \, \text{mm} \)
  - \( DE = 160 \, \text{mm} \)
  - The vertical distance between \( D \) and \( F \) is \( 200 \, \text{mm} \).

**Coordinate Axes:**
- The diagram defines the \( x \), \( y \), and \( z \) axes for clarity in spatial orientation:
    - The \( x \)-axis runs horizontally.
    - The \( y \)-axis runs vertically.
    - The \( z \)-axis represents the depth.

**Objective:**
Calculate the tension in the wire \( DF \).

This problem is a classic example of equilibrium in structural engineering, where the sum of forces and moments needs to be analyzed to ensure stability and determine unknown quantities like wire tension. This exercise will involve applying principles from statics, specifically the equilibrium conditions for systems subjected to concurrent forces.
