[SOLVED] spring-coupled masses
Thanks, Doc Al... I think I understand it now!
What matters is how much each spring is stretched (or compressed). So the total spring potential energy is given by your second expression. (This is explained on the page that you linked.)
There's a first time for everything. That's a tautology almost. But this type of reply, by editing the very first post, is a first for me in the forum. The answer is left hanging with part of the query missing. I can't but help ask why?
If you are interested in the question, the entire question is quoted in Doc Al's post, and I managed to understand it by myself, so there is no need for other people to waste their time on it...that's why I deleted it.
The more elegant way would be to mark the post as SOLVED.
Separate names with a comma.
