Elliptic Gears

Requires a Wolfram Notebook System
Interact on desktop, mobile and cloud with the free Wolfram Player or other Wolfram Language products.
Elliptic gears can be used to transform constant rotation into nonconstant rotation. When the orange gear rotates at a constant rate the blue gear rotation is first slow and then fast.
