Question
**Assignment Overview:**

**Instructions:**
You must use the Homework Procedure for this assignment. Solutions must be based solely on the method of joints.

**Problem Statement:**

1. The suspended object has weight \( W \). Both \( W \) and the dimension \( d \) are given. Member \( BG \) is a cable. What is the force in member \( CF \)?

**Diagram Explanation:**

The diagram illustrates a structural framework consisting of several members connected at joints. 

- **Members and Joints:**
  - The framework is mounted on a wall at point \( G \).
  - Member \( AB \) is perpendicular to the ground and vertically fixed between \( A \) and \( B \).
  - Member \( BG \) is a cable connecting \( B \) and \( G \).
  - Members \( BC, CD, DE \), and \( EF \) form a truss, with \( CD \) being horizontal, and \( DE \) and \( EF \) being inclined.
  - Member \( CF \) is part of the truss, running diagonally between joint \( C \) and joint \( F \).

- **Dimensions:**
  - The horizontal spacing between joints \( B \), \( C \), and \( D \) is \( d \).
  - The vertical spacing between joints is indicated as \( d \) or \( 2d \) where appropriate.
  
- **Load:**
  - A weight \( W \) is suspended from joint \( D \), creating tension in the structure.

**Objective:**
Determine the force in member \( CF \) using the method of joints, considering the structural equilibrium under the given load \( W \).
