Load on Structures

Civil engineers primarily deal with beams in their day-to-day applications. A beam is a structural member that resists shear loadings. There are various types of beams such as cantilever beam, simply supported beam, and over the hanging beam. All these beams have a different end and loading conditions.

Question

6–48. Determine the force in members JK, CJ, and CD of the truss and state if the members are in tension or compression.

answers: FJK = -11.1 kN (Compression); FCD = +12 kN (Tension); FCJ = -1.60 kN (Compression)

## Truss Analysis Problems

### Problem 6-48
Determine the force in members **JK**, **CJ**, and **CD** of the truss and state if the members are in tension or compression.

### Problem 6-49
Determine the force in members **HI**, **FI**, and **EF** of the truss and state if the members are in tension or compression.

### Truss Diagram Explanation
The truss is supported at points **A** and **G** and is structured with various members connecting joints labeled **A** through **L**. The height of the truss is 3 meters.

- Distances between supports and connection points are labeled as follows:
- From **A** to **B** is 2 meters
- **B** to **C** is 2 meters
- **C** to **D** is 2 meters
- **D** to **E** is 2 meters
- **E** to **F** is 2 meters
- **F** to **G** is 2 meters

- External forces acting downward on the truss are located at:
- **B** with a force of 4 kN
- **C** with a force of 5 kN
- **E** with a force of 8 kN
- **F** with a force of 6 kN

The members connecting these points form a framework that needs to be analyzed for forces, typically conducted to determine structural stability and material requirements.
