V-shaped Inclined Track with two objects: Cylinder and Double Cone

The cylinder when placed at the top of the track rolls to the bottom as its center of mass moves toward its point of lowest potential energy. The double cone when placed at the bottom of the track has its center of mass above the track. Therefore the cone moves uphill and as the track widens, the cone's center of mass is lowered until it can no longer move uphill. Bigger Version: Heb 18 Mech Updated on: 06/12/13
