Chaotic Pendulum

Drive amplitude = 0.50

The pendulum swings under the influence of gravity, a linear damping torque, and a periodic driving torque with an adjustable amplitude. Explore the behavior for different values of the drive amplitude.

As suggested by Giordano and Nakanishi, the damping constant is 0.5 and the angular frequency of the driving torque is 2/3, in natural units where g/L = 1.
