SwingingAtwood

Description

The swinging Atwood machine couples a pendulum to a vertically moving mass via a single inextensible string over a pulley. Competing exchanges between vertical and angular motion create a rich mixed phase space with coexisting regular islands and chaotic seas, providing a canonical laboratory example of low-dimensional Hamiltonian chaos and resonance overlap.
