I'm choosing to believe it's the parents causing the lock-up in that image.

That really grinds my gears!
For those that don't get it
The way the gears are arranged will result in a grid lock - you won't be able to turn any of them.
Rotating one clock-wise (CW) will rotate another counter-clock-wise (CCW), and the 3rd gear will spin CW. Because the first and 3rd gear are close enough to be in contact, and they're both rotating CW, they are opposing each other resulting in them being locked
Ie. none of this will work
Yup on a 2 dimensional surface or if all three share a plane it’ll never work. Only way would be if one was extruded and the other two weren’t touching.
Where do I read more a out the theory behind this?
Is there a way to arrange three gears in a way that won't lock up (maybe in a line)
Any wat in which 1 and 3 are not in contact with each other. Lines work. 2 being double thickness and 1 and 3 having depth separation works.
Gears are really simple and absolutely something more people should understand
Nothing is more simple than American's, I'm afraid. We've been losing a war on education for around 70 years now.
"American's", ironic
Making the 2 smaller ones not touch each other or one of the small ones not touching with the big one would do it
