Gravity force acting on masses and springs

In summary, the mass m3 does not fall because it is a one-dimensional motion problem with guides or constraints acting that are not shown. This is likely a top view looking down on a frictionless table and not a hanging cantilevered setup. The rules of the Homework Help forums explain why this problem should be posted there for assistance.

Thank you berkeman for your reply. In the exercice they don't talk about table.berkeman said:

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.
Related to Gravity force acting on masses and springs
1. What is gravity force?
Gravity force is the force of attraction between two objects due to their mass. It is one of the four fundamental forces of nature and is responsible for keeping planets in orbit around the sun and objects on Earth from floating off into space.
2. How does gravity force act on masses and springs?
Gravity force acts on masses and springs by pulling them towards the center of the Earth. It affects all objects with mass, regardless of their size or composition. In the case of springs, gravity force may cause them to stretch or compress, depending on their orientation and the direction of the force.
3. What is the relationship between gravity force and mass?
The greater the mass of an object, the greater the force of gravity acting on it. This means that the force of gravity on a larger, more massive object will be stronger than on a smaller, less massive object. However, the distance between the two objects also plays a role in determining the strength of the force.
4. How is gravity force related to the distance between objects?
The force of gravity between two objects is inversely proportional to the square of the distance between them. This means that as the distance between two objects increases, the force of gravity between them decreases. This relationship is known as the inverse square law.
5. Can gravity force be cancelled out?
No, gravity force cannot be cancelled out. It is a fundamental force of nature and is always present between objects with mass. However, other forces, such as electromagnetism, may counteract the effects of gravity force in certain situations.
