Direction of reaction of a support

Click For Summary
SUMMARY

The direction of the reaction force in structural mechanics is determined by the state of the member in question, specifically whether it is in tension or compression. When a member is in tension, the reaction force typically acts away from the member, while in compression, it acts towards the member. Understanding these principles is essential for accurately analyzing forces in static equilibrium scenarios.

PREREQUISITES
  • Basic understanding of static equilibrium
  • Knowledge of tension and compression in structural members
  • Familiarity with free body diagrams
  • Concept of reaction forces in mechanics
NEXT STEPS
  • Study the principles of static equilibrium in detail
  • Learn how to draw and interpret free body diagrams
  • Explore the differences between tension and compression in structural analysis
  • Investigate real-world applications of reaction forces in engineering
USEFUL FOR

Students of engineering mechanics, structural engineers, and anyone involved in analyzing forces in static structures.

You give little information. Is the short member in tension or compression?

This is my notes. I have no idea. Can you explain when the reaction is acted to the left ? Or when is tge reaction acted to the right? Compreession or tension?
