Is there an explanation why the smaller arm never spins clockwise? It almost does but always swings back before completing a full turn. It might be even a half turn or less than a full 360 but it’s at least bounded at less than a full turn clockwise in this video.
In my advanced mechanics course we discussed it in a student presentation. I don’t remember how much of a pain the equations of motion were, I can probably still look up the recording of it.
There was an [art installation](https://youtube.com/watch?v=cYWvH06oQiM&feature=share) called ‘mobilarium’ somewhere in the Netherlands that used this principle but with 2×3 moving parts, driven by wind. Sadly it was torn down a few years ago and has been stowed away somewhere since.
Ah yes, this is one of those systems where technically if you have all the values measured you should be able to predict its next step, but a small error in measurement leads to wildly different realities.
It’d be similar to a double pendulum, right?
Anyone else think of that scene in Iron Man 2?
Well, well, well. Guess who just created a homework problem
This is great! And the little swing in the bonsai is the most adorable thing I’ve seen today!

fold, shift, mutilate……..gives me a headache just thinking about the math.
Would be better if the bar were inline with each other. Think about the lateral torques happening in this thing, it’s annoying.
having classical mechanics 2 flashbacks lol…. I actually liked that class. You feel like a mathematical badass.
I have three of these going all the time. I replace the 4 AA batteries every few months and it’s totally worth it.

I want to and have the formulas lying around but I’m too stupid to do it.
It’s so nice to see things that could make us think of constant motion

Me too! I love bonsai trees. That spinny thing keeps blocking my view.
What is this object called? I want one.
This reminds me so much of QWOP
Why is there not a little person sitting in the swing watching the funmill?
I wonder how long does it work without batteries it you just poke it
Where do I get this
