I wanted to know if anyone of you do know a book or article on the Internet in which the equations of motion of a double pendulum is deduced, only using vector methods (i.e. Newton's 2nd law as opposed to Lagrangian formalism).

This question appears to be off-topic. The users who voted to close gave this specific reason:

  • "Homework-like questions should ask about a specific physics concept and show some effort to work through the problem. We want our questions to be useful to the broader community, and to future users. See our meta site for more guidance on how to edit your question to make it better" – tpg2114, jinawee
If this question can be reworded to fit the rules in the help center, please edit the question.

  • $\begingroup$ Unfortunately this question doesn't really abide by either the homework policy or the book request policy... not sure of the best way to make it conform to either though. I recall doing this problem in my system dynamics class, and it was rather unpleasant, but I sold that book years ago so I can't help you with that... $\endgroup$ – tpg2114 Feb 25 '14 at 3:14
  • $\begingroup$ Thanks for the help anyway, at least I can start by looking in system dynamics books. I start to do, however, is quite rude and operations are too, to the point where I lost them and opted for a book or search on the net but just have not found anything. I could upload my procedure and wait for someone to check but it is quite long and not want to take the time to other people with my operations, hehe $\endgroup$ – user40658 Feb 25 '14 at 3:52

    $\begingroup$ This question appears to be off-topic because it isn't about any physics concept and doesn't fit our book policy. $\endgroup$ – Brandon Enright Feb 25 '14 at 4:10
  • $\begingroup$ "Check my work" type questions would be off-topic too... If you could boil it down to a concept you are struggling with specifically though, that would be on topic. But my guess is you might just be stuck in the algebra because it's fairly tedious. Newton's 2nd law is fortunately "simple," but tedious as anything to keep the signs correct. $\endgroup$ – tpg2114 Feb 25 '14 at 4:13
