PIRA Classification: 3A95.50
Description: A double physical pendulum is constructed from bars of aluminum. When the pendulum is given a small initial displacement, its motion is predictable. When the pendulum is given a large initial displacement, its motion becomes chaotic. A second pendulum is mounted on the same stand. Start both with the same initial conditions and wait to see how long it takes for them to diverge from each other.
