Grampa Strutts made a similar machine out of wood with tapered wood dowels instead of prism-shaped dogs based upon the 2nd .gif. It’s the basis of a 4-stroke engine. The top one I messed with and added 4-colors only because someone elsewhere complained that B&W didn’t make it.
I love this stuff. I might have to add a category for Trig/Geometry/Math.
Any website called “Trigonometry Is My Bitch” that includes an inverse hyperbolic tangential hailstorm .gif gets an instant link on our sidebar. Tangents rule in my world, and I’m off on another one.

Steamboat McGoo found this excellent study illustrating the importance of understanding basic geometry. Although the explanation is in Japanese, it’s of critical importance that angle TQS is equal to angle AQE in order to cause the schoolboy’s jaw to drop.
There’s a pun in there somewhere about an extra riser, but I’m not gonna go there.
[Whoa. Just found the source of that excellence. There are a series of Manga textbooks, and they’re available in other languages including Portuguese. Tip o’ the tarboosh to mars for the update.]
