PIRA Classification: 1Q20.18
Description: Two rods are allowed to swing (independently from
each other) from a horizontal support. When the two are released from the
same height, they obtain the same motion. A mass can be added to the
end of one rod.
When the rods are brought to the same height and released, the simple rod
reaches the bottom first.
Special Instructions: Perform this demo a few times with the
mass at different positions, changing the moment of inertia of the system.
