• Resumen

  • Resonance is a topic included in most introductory physics courses. Any mechanical system experiences resonance if it is driven by a periodic force with a frequency that matches its natural frequency. There are plenty of simple demonstrations of the resonance phenomena of mechanical systems that can be set up using readily available items.1–5 Here I present a very simple approach to demonstrate the phenomena using just two spring scales. The experiment presented here performs a “frequency sweep” and is also very entertaining to watch.
