Pull Yourself Up (Three-Seat)
★Exhibit Content: Pulley System ★Interaction: Mechanical Interaction ★Operation: Approach the exhibit, visitors sit on the seat and pull the rope, then switch to another seat and pull the rope to feel the difference in force required for different seats. ★Exhibit Description: The exhibit consists of a frame, pulley system, pneumatic buffer mechanism, and seats. The three sets of devices are respectively set to three labor-saving modes. Participants sit on the chair and pull themselves up; through the difference in the number of fixed pulleys and movable pulleys, they can feel that as the movable pulleys increase, pulling themselves up becomes increasingly labor-saving. ★Scientific Principle: Without much effort, one can lift oneself up, which utilizes the principle of pulleys. A pulley system consists of movable pulleys and fixed pulleys. According to the principle of pulley systems, fixed pulleys can change the direction of force, movable pulleys can save effort, and their combined use both saves effort and changes the direction of force. A pulley whose central axis is fixed and immovable is a fixed pulley. A fixed pulley is essentially an equal-arm lever; its characteristic is that it cannot save effort but can change the direction of force. A pulley whose axis moves with the pulled object is called a movable pulley. A movable pulley can save half the effort but cannot change the direction of force. If a movable pulley is lifted by several strands of rope, the force used is a fraction of the weight of the object.
