Block and tackle with four pulleys
Article no. P1001100 | Type: Experiments
Using a block and tackle as an example, the students should observe that the force, which is necessary to lift a given load, decreases in direct correlation with the number of pulleys.
- They should determine how much larger the weight force of the load is compared to the force which is necessary to maintain equilibrium, and whether there is a connection between this and the number of pulleys of a block and tackle.
- They should investigate whether the load distance differs from the force distance and form the product F × s.
Additionally, they should be able to say whether the number of pulleys is important here, too.
