Syncronizing Metronomes

    Can anyone literate in physics explain this to me?  The metronomes are sitting on a moveable table–you can see it start to swing.  I guess the table allows for the transference of kinetic energy.  But how do they all synch up?

     On the YouTube video, one commenter, SenatorT1, explains it thusly:

Like neighboring guitar strings, the vibrations´╗┐ of one oscillator radiates mechanical energy because of the loose coupling of the base board. Leading oscillators tend to be held back by lagging neighbors, and energy equalizes amongst them until all are in perfect synchrony where the exchange stops and no further transfer one way or the other occurs because they are all in sync.

Basic physics at work.

       I don’t understand why the leading oscillators are held back by lagging neighbors!  Why?  Is it the drive towards inertia?

       I found this video linked on Maggie McNeil’s blog.  

           Science is awesome!

  1. Hello Margo!

    Amazing Video! I did a little research by myself and found this one:

    I think even if it is less amazing you can see the mechanics better as the surface is moving more obviously. A short explanation is from the uploader given.
    I imagine it like this: think about metronomes/inverse pendulums that don’t move. Now move the thing where they stand on. You will move the base of the metronome and the top head will follow. And all metronomes in the same frequency you initiated. If you look now at the video you see regardless how many metronomes you have on the moveable plate the plate will react with one frequency. That’s basically all.

    best wishes!
