Modern Catapult
★Exhibit Content: Practical Applications of Mechanics ★Interaction: Mechanical Interaction ★Operation: 1. Build your own target by hand. 2. Use the sandbag to hit the target with the catapult. ★Exhibit Description: This exhibit is equipped with two sets of catapult devices, sandbag projectiles, and a building block area. Visitors can freely build targets in the block area, operate the catapult to aim and hit the targets. The exhibit utilizes the principle of lever torque transmission, relying on the rotation of the lever arm to convert human power into sandbag projection power, intuitively demonstrating the relationship between lever arm, torque, projection distance, and force. During the interactive process of aiming and throwing, visitors exercise hand-eye coordination and spatial distance judgment, and the competitive mode enhances the fun of interaction. ★Scientific Principle: The catapult is a lever device. Changes in the lengths of the power arm and resistance arm affect the magnitude of torque. Applying external force drives the lever to swing, accumulating kinetic energy and transferring it to the sandbag, converting mechanical energy into the kinetic energy of the sandbag, achieving long-distance projection of objects, and intuitively demonstrating the laws of lever mechanics.
