A pendulum consisting of a mass fixed to the end of a (massless) rod can exhibit complicated motion when driven by an external force and with possible damping. This Demonstration explores the range of resonant, transient and chaotic behavior that this simple system can exhibit. After selecting the various parameters, click the "run" arrow to set the pendulum in motion.
