Homework Help: 5 spring coupled masses

  1. Jan 9, 2012 #1
    Hey,

    I've been trying to do this question out of Classical Mechanics by Goldstein

    http://img193.imageshack.us/img193/7747/asdasddh.jpg [Broken]

    Initially i started doing it like you would a three coupled system writing out the lagrangian and I didn't take notice to the hint it provides.

    I'm having trouble understanding the hint, i know η is supposed to be the position with the addition of a small increment, but then im not really sure what ζ is. It just reads in the text that its another transformation with η=aζ.

    How come a=1 for mass 3 and how do you use what they have given for η?

    For mass 2 and 4 are their values of η just equal and opposite?

    Thanks in advance for any help
