A simple machine with a rope wound round an
axle connected to a larger wheel with another
rope attached to its rim. Pulling on the
wheel rope (applying an effort) lifts a load
attached to the axle rope. The velocity ratio
of the machine (distance moved by load
divided by distance moved by effort) is equal
to the ratio of the wheel radius to the axle
radius.
