Question
Determine the force in each member of the truss, and state if the members are in tension or compression. We have a pin at A and a roller at C.

Transcribed Image Text:The image depicts a structural diagram of a square frame with applied forces. The frame consists of horizontal and vertical members, labeled as AB, BC, CD, and DA, forming a square with each side measuring 2 meters. There is also a diagonal member AC connecting opposite corners of the square.
### Forces Applied:
1. **Point A:**
- The frame is supported at this point, represented with a fixed base symbol.
2. **Point B:**
- A horizontal force of 250 N is applied to the right.
- A vertical downward force of 200 N is also applied.
3. **Point C:**
- This point is connected to a wall surface, indicated by support symbols.
4. **Point D:**
- A horizontal force of 400 N is applied to the left.
- Additionally, a vertical downward force of 300 N is applied.
### Structural Elements:
- The square frame is oriented such that AB and CD are horizontal members, while BC and DA are vertical members.
- Member AC acts as a diagonal brace within the frame.
This diagram is used to illustrate the equilibrium conditions of structures under various force applications, helping in understanding the distribution and effects of loads on structural frameworks.
