Gravity force acting on masses and springs

Click For Summary

Discussion Overview

The discussion revolves around the question of why a specific mass, referred to as m3, does not fall in a given scenario involving masses and springs. Participants explore the setup and constraints of the problem, which appears to involve a frictionless table and possibly other guiding forces.

Discussion Character

  • Exploratory
  • Homework-related

Main Points Raised

  • One participant questions why mass m3 does not fall, suggesting a possible top view of a frictionless table.
  • Another participant acknowledges the initial question and notes that the exercise does not specify a table.
  • A participant humorously remarks on the unusual setup if the masses were cantilevered off to the right.
  • One participant clarifies that m3 does not fall due to it being a one-dimensional motion problem, implying the presence of constraints not depicted in the problem.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the specifics of the problem setup or the reasons for m3's behavior, indicating multiple competing views and unresolved aspects of the discussion.

Contextual Notes

The discussion lacks details about the assumptions regarding the forces acting on the masses and the specific configuration of the system, which may affect interpretations.

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.
