AI Thread Summary
The Rayleigh Dissipative Function is a concept in Lagrangian mechanics that introduces dissipative effects, such as friction and electric resistance, into the equations of motion. It allows for the incorporation of non-conservative forces in a systematic way. The discussion highlights the importance of understanding this function for a deeper grasp of classical mechanics, with a specific reference to Goldstein's "Classical Mechanics" as a valuable resource for further study.

Physics people,

what is the theory behind the Rayleigh Dissipative Function? could you kindly give me some website which could help me understand this?

All I remember is that you use Rayleigh dissipation function to introduce dissipative (non-conservative) effects like friction, electric resistance etc. into Lagrangian mechanics. The only reference I can give you offhand is Goldstein's Classical Mechanics.

dg,

thank you very much for the information... :) I'm now reading the goldstein's classical mechanics..
