G2-12: BARTON'S PENDULUMS

ID Code: G2-12
Purpose: Demonstrate driven resonance.
Description: A set of non-coupled pendula are placed on a platform that rocks at the same frequency as one of the center pendula. The rocking motion drives the motion of the pendulum with which it is resonant, but only partially drives the others, showing systematically how a vibrating system responds when the natural frequency is below, at, and above the driving frequency, as seen in the photograph at the right.
