Lagrangian Mechanics: Constrained Systems Q&A

Click For Summary
SUMMARY

The discussion focuses on the application of the Lagrange multiplier method within the context of Lagrangian mechanics, specifically for constrained systems. Participants explore how Lagrange multipliers facilitate the identification of extrema of the Action functional, which is crucial for understanding the dynamics of systems with constraints. The conversation highlights the mathematical foundation necessary for applying this method effectively in physics.

Is anyone good with Lagrangian mechanics applied to constrained systems?

I had a question about the Lagrange multiplier method, maybe I should have posted it in this section.

Are you asking why Lagrange multipilers are a way to do constrained minimization?
 
I'm asking how is the method of Lagrange Multipliers (which is used to find the extrema of level surfaces subject to constraints) used to find the extrema of the Action functional.

I thought I'd be more of a math question but nobody there is throwing me an answer.
