[math-fun] gears

Yes, gears (if designed right) do attain constant angular velocity and contacting 100% of time. However, unlike wheels they do not "roll"; they always slide. The theory shows this is inevitable. See this paper by me to learn about gear theory and the least-friction gear curve (found by me) which could use some numerical exploration...: http://rangevoting.org/WarrenSmithPages/homepage/works.html paper #23. -- Warren D.
