Resonance Demonstrator

Forced Vibration Demonstrator – Bring Resonance to Life!This 3D-printable Forced Vibration Demonstrator is a simple yet powerful tool for visualizing the phenomenon of forced vibrations and resonance. It’s perfect for classrooms, labs, or science fairs, where you want to show complex physical concepts in an intuitive, hands-on way.The model consists of a sturdy base with three vertical flexible rods of different lengths, each topped with a round counterweight. The rods are labeled Low Frequency, Medium Frequency, and High Frequency, making it easy to compare their behavior side by side. When you move the base rhythmically, each rod responds differently, and at just the right rhythm one of them will swing strongly due to resonance. The effect is immediate, striking, and easy to grasp.👉 Assembly Tip:The circular counterweights are designed to be loaded with two M10 threaded nuts each. These can be placed directly into the printed parts without glue. Simply set a pause in your slicer so
