Bouncing and Arching Balls
★Exhibit Content: Mechanical Transmission ★Interaction: Mechanical Interaction ★Operation: 1. Place the ball into the ejection device, press the handle to launch it into the central ball collector; 2. Place the ball into the track transport device, operate the handle up and down to move it to the central ball collector; 3. Place the ball into the projection device, press the handle to throw it into the central ball collector. ★Exhibit Description: The exhibit mainly consists of a shaped display stand, ejection mechanism, projection mechanism, arching mechanism, and other three types of interactive mechanisms. The ejection mechanism, under the action of elastic force, ejects the small ball into the central ball collector; the projection mechanism, by applying force to the projection mechanism, changes the motion state of the small ball and projects it into the central ball collector; the arching mechanism, by operating the handle up and down, transports the small ball to the ball collector. ★Scientific Principle: Mechanical transmission mechanisms can change the mode, direction, or speed of motion provided by power, and are purposefully utilized by people. There are many types of transmission mechanisms in ancient China, mainly gear transmission, rope and belt transmission, and chain transmission.
