Triple Parallel Pulleys, Set of 2
Product Code: PP555_S2
Two, triple parallel plastic pulleys can be combined to form a triple
fixed/triple moveable block and tackle pulley system. These pulleys have
sheaves with deep V-grooves with diameters of 50 mm.
Same as 2PULLEY555.
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.
The picture shows a block and tackle design using twisted mason twine (100%
Nylon) along with a weight, both of which are not included.
