3A60.30 - Barton's Pendula

Code Number:
3A60.30
Demo Title:
Barton's Pendula
Condition:
Good
Principle:
Simple Harmonic Motion
Area of Study:
Acoustics
Equipment:
Barton's Pendula Apparatus.
Procedure:

Adjust the large driving pendula to a desired height and set into motion. After a few oscillations one of the pendula should be oscillating in resonance with the driving pendula, but almost 180 degrees out of phase.
