Snake Pendulum (Cabinet)
★Exhibit Content: Dynamics and vibration phenomena ★Interaction: Electromechanical interaction ★Operation: Press the start button, the flap rotates to make the pendulum balls swing freely simultaneously, and observe the motion state of the pendulums. ★Exhibit Description: The exhibit consists of a display stand and a row of simple pendulums. The pendulum lengths are all different. We can observe that the pendulums gradually change from free swinging to snake-like swinging. The period of a simple pendulum is related to its length; the longer the pendulum, the longer the period. In the exhibit, because the pendulum lengths are different, the periods are different. As the number of swings increases, a neat row of pendulums becomes a snake-like pendulum. ★Scientific Principle: In this exhibit, the pendulum lengths decrease regularly, so the periods of all pendulums also decrease regularly. In terms of swing angle, the swing angles also decrease regularly. Therefore, after starting, initially because the angle differences are small and regular, it appears as a wave-like swinging. After many swings, the differences gradually increase and appear chaotic. As swinging continues, until the angles of odd and even pendulums reach integer multiples and half-integer multiples respectively, a situation of splitting into two sides can be observed.
