About This Product
Pulleys show students how a cord changes the direction of a force and how a movable pulley reduces the effort needed to lift a load. With spring balances and weights, the class measures effort, load and tension in different arrangements and works out mechanical advantage and efficiency.
Frequently Asked Questions
Can the pulleys be used as movable pulleys?
Yes. For movable pulley experiments the pulley is attached to the load and the string is arranged around it, so effort can be compared with the load lifted.
