Snake Pendulum (Tabletop)
★Exhibit Content: Dynamics and vibration phenomena ★Interaction: Mechanical interaction ★Operation: Turn the handwheel to flip the board, causing the pendulum balls to swing freely simultaneously, and observe the motion of the pendulums. ★Exhibit Description: The exhibit consists of a platform and a row of simple pendulums. The lengths of the simple pendulums 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 length, the longer the period. In the exhibit, because the lengths of the pendulums are different, their 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 lengths of the simple pendulums 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 to swing, 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.
