# Project that is similar to the coupled pendulum

I am doing a project that is similar to the coupled pendulum (http://www.her.itesm.mx/academia/profesional/cursos/fisica_2000/FisicaII/PHYSENGL/cpendula.htm [Broken] but with springs instead of pendulum. My problem is that I am required to give background theory and the address of sites I got it from, but I don't know any and all the search engines I have tried seem to have no results. My teacher has never seen anyone do this project this way before and said if worse comes to worse I must roughly use the info on coupled pendulum. But as that goes into the angle of the pendulum (which springs don't have) it doesn't help much. Can you please help as soon as possible (as it is due in soon). Thanks!

If the spring does not have an angle to it then the system is not very interesting. Two masses that jiggle up and down with a spring between them is just a coupled oscillator.

On the other hand if there is a angle for the spring the system is more interesting and harder to find information on.

Near the end of the web page there is a problem similar to yours:

If you do have time you can look up Lagrangian or Hamiltonian dynamics and find the equation of motion.

I did a search on the web for other resources and did not come up with much so if you do not have time for Lagrangian or Hamiltonian dynamics you may be out of luck.

Help!
I don't want to create another topic,just for a little need of help.So i decide to post my trouble in this topic.Plz forgive me if you mind.

I have recently done on Theoretical Mechanics.And i find it very hard to solve the problems in this subject (may be it too strange).

So i have to practise more on this subject.And the problem 's i can find any book that contain problems.I have some books but they're too hard for me.
I'm from Vietnam,it's hard too find a good book in our country.I can only find it on Internet.Can anyone help me???
