A random mix of wheels shaped as either circles or Reuleaux triangles. Click the green flag to randomize them.
< < < Disclaimer > > > The imperfections are due to the fact that the Reuleaux triangles are only approximate because I drew them manually in the Scratch paint editor. If they were perfectly shaped, the wheels would be in contact constantly. < < < Notes > > > Note the movement of the axle (the large dot in the center) and the smaller dot on the wheel itself. With a circular wheel, the axle is fixed, and the smaller dot moves in a perfect circle. With a Reuleaux triangle wheel, the axle moves in a perfect circle, and the smaller dot moves in a square with slightly rounded corners. The following project by @good_coder_bad_boy illustrates these interesting movements in several ways: https://scratch.mit.edu/projects/526845200/ This project by @haruni459 is another great demonstration: https://scratch.mit.edu/projects/873615207/
