1. The fixedpulley - requires more effort than the load. 2. The movable pulley - moves with the load which allows for less effort than load. 3. The combined pulley - effort is less than half the weight of the load

What are the three parts of a pulley?

The three parts of a pulley are the wheel, the axle, and the rope or cable that runs over the wheel. The wheel is the round disc that rotates on the axle, the axle is the central rod that the wheel spins on, and the rope or cable is what is pulled to move objects.


What are the three different types of pulleys?

The three types of pulleys are fixed pulleys, movable (or movable) pulleys, and compound pulleys. Fixed pulleys change the direction of the force applied, movable pulleys provide a mechanical advantage by reducing the force needed, and compound pulleys combine fixed and movable pulleys for increased mechanical advantage.


Why it is easier to lift the same load by using three -pulley system than two-pulley system?

A three-pulley system allows the load to be distributed among three supporting strands, making it easier to lift the load as each strand bears less weight compared to a two-pulley system where the load is evenly distributed between only two strands. The mechanical advantage of the three-pulley system reduces the amount of force required to lift the load, making it easier to lift.

What are the three kinds of pulleys and describe each briefly?

The three kinds of pulleys are fixed pulleys, movable pulleys, and compound pulleys. Fixed pulleys are anchored in place and change the direction of the force applied. Movable pulleys have a pulley that moves with the load, reducing the force needed to lift the object. Compound pulleys consist of multiple pulleys working together to provide mechanical advantage in lifting heavy loads.
