Corina Marinescu :) Even counting the circles (which is our area of expertise) is pretty difficult here. But I've found a gear ratio calculator: http://www.grimmjeeper.com/gears.html David Hallowell now you just need to insert a few numbers there ;)
David Hallowell Visualizing each gear as a vertex, there are: 12 Red gears with 20 teeth each (icosahedron) 20 Blue gears with 24 teeth each (dodecahedron) 60 Yellow gears with 13 teeth each (truncated icosahedron or soccer ball)
I know nothing about gear drives, but I can count teeth on a screen capture and I recognize a dodecahedron pattern when I see one. :o)
so brilliant idea. wish school kids get a project like this to make out gears. perfect understanding of machinery from early age.
