The effect of rotation in changing the shape of plastic bodies
can readily be shown in simple experiments. A light metal ring
is mounted on a vertical axis about which it can be rotated
with great rapidity. When the ring is at rest it is circular
in shape, but when it is rotated it becomes flattened along
the axis, bulging out at what we may call the equator. The
faster the ring is rotated the greater and greater becomes its
departure from circular shape.--CHARLES LANE POOR, “The
Solar System.”
