System of Pendulums: A Realization of the Sine-Gordon Model

A row of pendulums hang from a rod and are coupled by torsion springs. This system can be described by a nonlinear differential equation called the sine-Gordon equation. The solutions can exhibit different types of behavior, involving solitons, antisolitons, and their interactions.
