3A60.30 - Barton's Pendula

Code Number: 3A60.30
Demo Title: Barton's Pendula
Condition: Good
Principle: Simple Harmonic Motion
Area of Study: Oscillations & 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.
