Mechanical Resonance

This experiment consists of a mechanical driver that pushes a multi-spoked device and clearly shows mechanical resonance. The spokes have different lengths and therefore have different resonant frequencies so only one spoke will vibrate in resonance at a time for a given driving frequency.
