Purpose & Scientific Principle
The exhibition item uses the combination of fixed pulleys and movable pulleys to save labor and change the direction of force. The pulley is a simple machine. The fixed pulley changes the direction of force, and the movable pulley saves labor. The amount of effort saved is related to the number of strands passing through the movable pulley, that is: using several lengths of rope to hang an object, the force used to lift the object is a fraction of the weight of the object, and the distance moved by the pulling force is several times the distance the object moves.
How to Operate
The exhibition item consists of seats, fixed pulleys, movable pulleys, fixed brackets, buffer mechanisms, guide rails, etc. The exhibition item provides two seat operation positions. The pulleys on each seat are in different forms and are divided into: 1 set of fixed pulleys, 1 set of fixed pulleys and movable pulleys. Participants sit on the seat, pull the rope with their hands, and slowly lift the seat to experience the force exerted on the different moving pulleys to understand the role of the pulleys. (The more ropes that pass through the movable pulley, the less effort it takes). Through mechanical interaction, the audience can experience and understand the characteristics of fixed pulleys and movable pulleys. Fixed pulleys can only change the direction of force, while movable pulleys can save effort. Fixed pulleys and movable pulleys
The audience sits on different seats, pulls the rope with their hands, and the seat is slowly raised to experience the force exerted on the different moving pulleys.
