Can I ask you something?I find the same Lagrangian but the only difference is that the coefficient of x_1^2 is 3 and instead of the product x_1x_2 I found the product x_3x_1

Thanks for your reply, that's what I tried to do but I keep getting mixed up between the displacements for example what I found was this: mg(l+x_1 )+mg(2l+x_2 )+mg(3l+x_3 ) where x_1 is the closest to the ceiling mass and l is the length of each spring at rest. We consider all springs to...

Homework Statement Essentially the problem that I am trying to solve is the same as in this topic except that it is for 3 springs and 3 masses https://www.physicsforums.com/showthread.php?t=299905 Homework Equations I have found similar equations as in the topic but I face a problem in...
