Constructing and testing an inverted, periodically driven, damped pendulum to study chaotic motion

Following the work of Berger and Nunes Jr., we designed and built an inverted, periodically driven, damped pendulum, which can be a Duffing oscillator, to study the transition from periodic to chaotic motion. We performed magnetic field measurements to characterize the permanent magnets and electromagnets used to drive the pendulum. We also analyzed video recordings of the oscillator in motion to determine the damping coefficient and resonance frequency of the pendulum
