Gravity force acting on masses and springs

Click For Summary
SUMMARY

The discussion centers on the mechanics of mass m3 in a one-dimensional motion scenario, specifically addressing why it does not fall. It is established that the problem likely involves constraints or guides not depicted in the exercise. The conversation also touches on forum etiquette regarding posting schoolwork-related questions in designated Homework Help forums. The participants emphasize the importance of adhering to community guidelines while discussing physics problems.

PREREQUISITES
  • Understanding of one-dimensional motion in physics
  • Familiarity with the concept of constraints in mechanical systems
  • Knowledge of forum etiquette for academic discussions
  • Basic principles of gravity and forces acting on masses
NEXT STEPS
  • Research the role of constraints in mechanical systems
  • Study one-dimensional motion problems in classical mechanics
  • Explore the principles of gravity and its effects on different mass configurations
  • Review community guidelines for academic forums and effective question posting
USEFUL FOR

This discussion is beneficial for physics students, educators, and anyone interested in understanding the dynamics of forces acting on masses in constrained systems.

Hello
Please why the mass m3 does not fall?

That's probably a top view looking down on a frictionless table?

Thank you berkeman for your reply. In the exercice they don't talk about table.
 
You're welcome. Yeah, if the masses were hanging cantilevered off to the right like that, it would be a pretty weird setup. :smile:

If you have any other questions about this problem or other schoolwork problems, be sure to post them in the Homework Help forums, and fill out the Template you are provided there. :smile:

It's not homework, i just wondered when I read a book and did this exercise
 
More generally, M3 does not fall because it is a one-dimensional motion problem. There are guides or constraints acting that are not shown.
