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

Transcribed Image Text:## 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.
