SUMMARY

The discussion focuses on solving a practice problem related to a pin-connected frame in structural engineering. The main challenge is determining whether to treat the frame as two separate structures due to the presence of a central pin. Participants emphasize the importance of applying 2D equilibrium equations, specifically Fx, Fy, and M, to analyze the forces acting on the structure. The consensus is to start by creating free body diagrams (FBDs) for both sections of the frame to facilitate problem-solving.

PREREQUISITES
  • Understanding of 2D Equilibrium principles
  • Familiarity with Free Body Diagrams (FBDs)
  • Knowledge of force components: Fx, Fy, and moments (M)
  • Basic concepts of structural analysis for pin-connected frames
NEXT STEPS
  • Study the application of 2D Equilibrium in structural analysis
  • Learn how to construct and interpret Free Body Diagrams (FBDs)
  • Explore the principles of force equilibrium in pin-connected structures
  • Review examples of structural problems involving pin connections
USEFUL FOR

This discussion is beneficial for civil engineers, structural engineering students, and anyone involved in analyzing pin-connected frames and applying equilibrium principles in their work.

Have identified what i need to find, but not sure how to proceed since there is a pin in the centre, do I treat it as two separate structures?

Welcome to PF.

Per the PF Rules, you need to show your work before we can help. So yes, start by treating it as two separate structures and show the FBDs please. Thank you.

this is what I have, then based on this i was thinking that i could assume this:

Does that look right?
 
Sure. That is the force equilibrium for the right part. What else can you deduce?
