Physics Problem

[John Moonan <jmoonan@ix.netcom.com>]

The way to tell the cylinders apart is by their moment of inertia.  Both
weigh the same but the gold cylinder will have more weight at the ends
and less in the center than the aluminum one so its moment of inertia
will be higher.

You can determine which is higher or lower by spinning the cylinder
while it is on its side.  The aluminum one will take less force to spin
and will stop spinning quicker.
