Center of Mass: Plumb Line

Topics: Mechanics - Center of Mass

Equipment: Wooden tower with pivot joint and plumb bob hanging from second level.

Setup: The apparatus can lean one way or the other, while the bob will always hang vertically. If the tower leans too far, it will fall over.

The center of mass of this tower is always where the plumb bob is. The bob can make it to the end of the wooden base, but no further. If it goes past this point, the tower will fall.

Location: Shelf B-f6
