Lever
★Exhibit Content: Lever Principle ★Interaction: Mechanical Interaction ★Operation: 1. Participants are on both ends of the lever, one sits and the other pulls; 2. Apply force by pulling ropes at different positions to experience the change in force. ★Exhibit Description: The exhibit consists of a support column, a long lever rod, a passenger seat, multiple sets of hanging force application components, and an instruction board. It is a recommended exhibit from the PopsciCat Exhibit Store. Inspired by Archimedes' famous quote "Give me a fulcrum, and I shall move the world," the exhibit features multiple force application points on the lever rod. Visitors sit on the seat end, while another visitor pulls the hanging rope at different positions, personally experiencing the labor-saving effect brought by changes in the length of the power arm, and intuitively experiencing the wonderful mechanical action of the lever. ★Scientific Principle: The lever principle is an important principle of basic mechanics, with the formula: power × power arm = resistance × resistance arm. When the resistance and resistance arm are constant, the longer the power arm, the smaller the power required. This exhibit allows visitors to experience the effect of changes in the power arm on labor-saving by setting force application points at different positions, verifying the application of the lever principle, intuitively experiencing the working mechanism of a "labor-saving lever," and understanding the mechanical logic behind Archimedes' famous lever quote.
