Do you guys know of any website that has solved problems of Lagrange Mechanics?
ThanksHerbert Goldstein, Classical Mechanics (Addison Wesley, 2001) :)
Or Google around.
I wonder what book :) https://www.wlu.ca/documents/53853/NotesCh8.pdf [Broken] guys (in place 1) refer to.
Plenty universities have stuff online. http://www.physics.ox.ac.uk/Users/Yassin/mechanics/notes/note5aplusb_2011_v0.pdf [Broken] looks good.
