Gravity force acting on masses and springs

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.

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.

It's not homework, i just wondered when I read a book and did this exercise

Yeah, but the PF rules are that all schoolwork-type problems get posted in the Homework Help forums. This thread may help to explain why we have this policy:

More generally, M3 does not fall because it is a one-dimensional motion problem. There are guides or constraints acting that are not shown.
