Abstract

An instrument suitable for experimental studies of chaotic motion is described. It consists of a mechanical pendulum driven by both steady and alternating torques, together with interface electronics for data logging. An optical shaft encoder serves as the transducer for measuring the instantaneous pendulum coordinate. The entire system is controlled from a personal computer. Sample phase-plane and Poincaré plots are presented.
