Rolling Table

Consder a round table with the tabletop of radius R, the base of radius r, and of height h (height = distance from the tabletop to the base). This interactive simulation enables you to view the circle traced by the tabletop when the table is put on its "side" and rolled. The tabletop and the base travel along two concentric circles on the floor. The simulation computes the radius of each circle.
