Question

Calculate the forces in all members of the trusses shown using the method of joints.

## Problem 5.7

The diagram presents a structural system with several forces acting on it. Here’s a detailed description:

- **Points and Supports:**
  - Point A is at the bottom left, supported by a roller, allowing horizontal movement but restricting vertical movement.
  - Point E is at the bottom right, supported by a fixed support, restricting both vertical and horizontal movement.
  - Points B, C, and D are connected by members.

- **Forces:**
  - At Point B, a vertical downward force of 5000 lb is applied.
  - At Point C, a horizontal force of 4000 lb is applied towards the left.
  - At Point D, a vertical downward force of 6000 lb is applied.

- **Distances:**
  - The horizontal distance between Point A and Point D is 8 feet.
  - The horizontal distance between Point D and Point E is 8 feet.
  - The vertical distance from Points A and E to Point C is 12 feet.

This setup is typically used in statics problems to analyze the equilibrium of forces within a structure.
