(Polski) HOW IT WORKS?

Approach position no. 1 and pull the rope. Next, approach position no. 2 and perform the same action. What did you observe? How much strength did you have to use in both positions to pick up the same weight? You’ve just learned how a pulley, which allows to lift great loads with use of small force, works. The amount of discs used in the machine decides how much the force necessary to lift given load will be reduced. Machines that use this rule are used in mining, well drilling, sailing, and multiple other fields. Pulley for lifting loads appeared around year 800 BC in Assyria.
