Bar-Coupled Pendula
Purpose
To demonstrate a coupling resonance and to show normal modes.
Equipment
Bar coupled pendula, as pictured.
Images
Description
By starting either pendulum in motion in the plane of the picture, one observes transfer of the motion between the two pendula. One can also produce the two normal modes: both pendula moving in phase, or the pendula moving out of phase.
