Are Constraints Necessary in Hamiltonian Dynamics?

AI Thread Summary
The Hamiltonian method allows for the treatment of systems with constraints, but these constraints must be included in the final calculations for the equations of motion. Ignoring constraints can lead to incorrect results, as they play a crucial role in defining the system's dynamics. The initial confusion stemmed from a misunderstanding of the method's application. Clarification was provided that constraints are indeed essential in the Hamiltonian framework. Ultimately, the importance of including constraints in calculations was reaffirmed.

Hi there,

I'm reading on the hamiltonian method and it says we can ignore constraints? Is this true, or am I missing something here, so if we have a constraint in the system we do not have to include it in the final calculation for the equation of motion?

Hope someone could clear this up, thanks!

It would be beneficial if you gave a reference and a verbatim quote of the statement. Otherwise we are stabbing in the dark.
 
Nvm, I was wrong! Thanks anyways, we do include the constrain!
 
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...
