Center Of Mass - Hinged Stick Paradox
To illustrate the center of mass in a surprising way.
Hinged stick with clamp to attach to table, hammer, as photographed.
Let the students try it for a while before helping them to determine a solution.
Q: How can you hang the hammer from the loop on the bottom of the hinged board so that the board will stick straight out horizontally? A: Insert the handle into the loop so that the head of the hammer is pointing back toward the hinge.
