摘要:
An unconventional driven torsion pendulum influenced by gravity has been studied for chaos. Through the use of a symmetric differential capacitive sensor and a galvanometer, phase‐space trajectories were generated with anx–yrecorder. These were then later compared against output from a computer model of the system which has been further used to generate Poincaré sections, Fourier transforms, and time records. Sensitive dependence on initial conditions as a function of frequency and drive amplitude was demonstrated.
