How Do You Solve 2D Equilibrium of a Rigid Body?

Click For Summary
SUMMARY

The discussion focuses on solving the 2D equilibrium of a rigid body using the equations of static equilibrium: ƩFx=0, ƩFy=0, and ƩMo=0. Participants emphasize the importance of enumerating all forces acting on the body, particularly at point B, which involves treating it as a sum of horizontal and vertical reaction forces. A common point of confusion is the assumption of a moment at B, which should be clarified as unnecessary in this context. The solution process requires careful consideration of all forces to achieve equilibrium.

PREREQUISITES
  • Understanding of static equilibrium principles
  • Familiarity with force enumeration techniques
  • Knowledge of rigid body mechanics
  • Ability to apply the equations of equilibrium (ƩFx, ƩFy, ƩMo)
NEXT STEPS
  • Study the application of static equilibrium in rigid body analysis
  • Learn about reaction forces and their calculations in 2D systems
  • Explore common mistakes in equilibrium problems and how to avoid them
  • Practice solving problems involving multiple forces and moments
USEFUL FOR

Students in engineering mechanics, physics enthusiasts, and anyone involved in analyzing the equilibrium of rigid bodies in two dimensions.

The Attempt at a Solution


not sure what unknowns are
 
Physics news on Phys.org
Start by enumerating the forces.
 
If you do not know, treat it generically. Assume it is a sum a horizontal and a vertical reaction forces. Then solve for them independently.
 
ok I think I got it now. I was just confused and assumed there would be a moment at B. Thanks
