Point of application of generalized forces of constraint

AI Thread Summary
In Lagrangian Dynamics, the application of generalized forces of constraint is often assumed to occur at the location of the corresponding generalized coordinate. However, generalized coordinates represent the configuration of a system rather than specific points in space. This raises questions about the relevance of applying forces at these coordinates. The discussion highlights a lack of explicit mention in the literature regarding the point of application for these forces. Overall, the relationship between generalized coordinates and the application of forces needs further clarification.

In Lagrangian Dynamics, I assume that generalized forces of constraint are applied at the location of the corresponding generalized coordinate. I don't recall seeing anything explicit about the point of application in the text.

Not necessarily. The generalized coordinates represent a configuration of the system, not a point in space. So there may not be any sense in which a force can be applied "at" a generalized coordinate.

Thread 'Question about pressure of a liquid'

Thread 'Question about pressure of a liquid'

I am looking at pressure in liquids and I am testing my idea. The vertical tube is 100m, the contraption is filled with water. The vertical tube is very thin(maybe 1mm^2 cross section). The area of the base is ~100m^2. Will he top half be launched in the air if suddenly it cracked?- assuming its light enough. I want to test my idea that if I had a thin long ruber tube that I lifted up, then the pressure at "red lines" will be high and that the $force = pressure * area$ would be massive...

Thread 'Why is the 3 body problem unsolvable? And what will happen if someone solves it?'

I feel it should be solvable we just need to find a perfect pattern, and there will be a general pattern since the forces acting are based on a single function, so..... you can't actually say it is unsolvable right? Cause imaging 3 bodies actually existed somwhere in this universe then nature isn't gonna wait till we predict it! And yea I have checked in many places that tiny changes cause large changes so it becomes chaos........ but still I just can't accept that it is impossible to solve...
