Double Tandem Pulleys, Set of 2
Product Code: PP54_S2
Two, double tandem plastic pulleys can be combined to form a double
fixed/double movable block and tackle pulley system. These pulleys have
sheaves with deep V-grooves with diameters of 50 and 40 mm.
Same as 2PULLEY54.
Pulleys are often used as parts of compound machines. They function as helper machines, easing the lifting process. 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.
