*engineering *art *wtf
and i thought about wheels/metal

Adding video to channels (Art, Engineering, Wtf) - requested by GDGD.

My brain just shut down.

They remind me of the Gömböc, but with quite a different function.

Me too...

A Wankel-Rotor is NOT a Reuleaux Triangle!

Hmmm really hate this video....

Because even after watching it... i'm at a complete loss as to explain it... Geometry and Math never really been my particular thing... but still... feel just very dumb watching this...

I just posted this video that does a great job of explaining this shape:

You said Wankel.>> ^rottenseed:

I don't have one to shut down! *wheels (almost)

Adding video to channels (Wheels) - requested by ant.

This video and the acorn shape goes a long way to explaining chipmunk cheek physics

WITCHCRAFT!!!

I'm sorry but this is simply unacceptable.

There are two planes, the book, and the table.
When a point plants itself on the table, the book "rolls" along the opposite curved surface.
When the book gets to the end of a curve, it becomes a point, and then the table "rolls" along the opposite curved surface.

One thing; both planes MUST be parallel. As soon as the book is tilted or there's a floor flaw in the table, it fails to work.

How would a bowling ball shaped like this behave??

Well if it was shaped like this then it wouldnt be a bowling ball now would it ? If say, you where to use the material and manufacturing process used in making bowling balls, had one made in this manner, then it would be a much heavier version and when rotating have much more momentum. other then that. it'd be the same yet heavier.

Also, just because they have constant width doesn't mean their centre of gravity remains at constant height. They'd make for very wobbly balls -- or wheels.
