Pulleys are often used as parts of compound machines. They function as
helper machines, easing the lifting power. In fact, a pulley system can cut the
force necessary to lift a very heavy object in two, four, etc., depending on the
designed system. With these pulleys you can study and measure the force and
distance trade off with compound machines. These pulleys are good for science
experiments as well as functional tasks.
| Pulley Lines or Pulley Strings
You will need high quality strings or
ropes for your pulleys. This pulley requires a 2-mm string. Please see
the
available pulley lines and make sure you order the right size for
