B1-17: CENTER OF MASS - STICKS
Additional Info
- ID Code: B1-17
- Purpose: Illustrate the center of mass in a surprising way
-
Description:
There are two sticks identical in appearance, but one is uniform in density and the other is weighted at one end. Since the center of masses for each stick will be different, they will have different balance points. The professor can mark the sticks either at their center of masses or where it appears to be, leaving the student to explain the peculiar behavior of the weighted stick when it is balanced.
Questions: Which stick will balance at its center and why?
These sticks also do double-duty as part of the demonstration D2-04: MOMENT OF INERTIA RODS.
