Wilburforce & Double Pendulums Demonstrate Resonance // Homemade Science with Bruce Yeany

In our studies of Harmonic motion, my students always enjoy spending some time building some simple Wilburforce and double pendulums. They all depend on the concept of resonance and help to get the point across very easily. It makes it easier for understanding this concept in other applications where it is not quite as easy to view such as in sound or electrical applications.
