Resonance Ring

Mobile Science Museum · Mechanics & Kinematics

Operation: 1. Press the start button to activate the sound source; 2. Press the up and down buttons to adjust the frequency and observe the sequence of vibrations of rings of different sizes. Function Overview: The exhibit consists of a speaker device, five rings of different sizes, a control system, a protective cover, etc. Visitors press the start button to activate the sound source; press the up and down buttons to adjust the frequency and observe the sequence of vibrations of rings of different sizes. Scientific Principle: Why do the rings vibrate at different frequencies? The diameter and material of the ring together determine its natural frequency. In forced vibration, when the angular frequency of the periodic external force approaches the natural frequency of the system, the amplitude of vibration increases sharply. This phenomenon is called resonance.
