90-92p. Abstract: 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. ***______{For Hard Copy, Please visit Library.}________*** Resonance phenomena| Frequency measurement| Educational aids 0031-921X https://doi.org/10.1119/5.0098426 https://doi.org/10.1119/5.0098426 240508 20240508084836.0
