Is the principle of minimum action applicable to nonholonomic systems?

AI Thread Summary
The principle of least action, also known as Hamilton's principle, does not directly apply to nonholonomic systems as they are nonvariational and arise from the Lagrange-d'Alembert principle. Nonholonomic systems exhibit unique characteristics, such as energy conservation without momentum preservation and a complex relationship with Noether's theorem. Additionally, while they are almost Poisson, they do not fully satisfy the Jacobi identity, affecting their dynamics. The phase space in nonholonomic systems may not preserve volume, leading to interesting stability behaviors despite energy conservation. This complexity highlights the distinct nature of nonholonomic systems in classical mechanics.

Hello

Is the principle of minimum action applicable to nonholonomic systems? Why?

If this question is already answered in this forum, just tell me, and I will delete this thread.

Thank you for your time :)

PS: My mother language is not English, so I'll be glad if you correct any mistake.

Sorry, that was an old expression; the modern one is "principle of least action" (or stationary action).

It is known as Hamilton's principle in classical mechanics :)

I googled the terms, and found

"There are some fascinating differences between nonholonomic systems and classical Hamiltonian or Lagrangian systems. Among other things: Nonholonomic systems are nonvariational - they arise from the Lagrange-d'Alembert principle and not from Hamilton's principle; while energy is preserved for nonholonomic systems, momentum is not always preserved for systems with symmetry (i.e., there is nontrivial dynamics associated with the nonholonomic generalization of Noether's theorem); nonholonomic systems are almost Poisson but not Poisson (i.e., there is a bracket which together with the energy on the phase space defines the motion, but the bracket generally does not satisfy the Jacobi identity); and finally, unlike the Hamiltonian setting, volume may not be preserved in the phase space, leading to interesting asymptotic stability in some cases, despite energy conservation."
 
Hello

Thank you so much for the links. I didn't know that this issue was so complex :)

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...
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...
