FLYBALL GOVERNOR
APPARATUS
flyball governor

DESCRIPTION
A pair of lead balls can be set
spinning
about the central axis. Squeezing the handle draws the balls
closer
to the axis of rotation, reducing the system's rotational inertia and
making it rotate with a greater angular velocity.
The faster the balls are spinning
initially, the harder it is to squeeze the handle.
