Pendulum model displays the motion of a two-part pendulum and
its Poincare map. A double pendulum is a simple pendulum with
another pendulum attached to its end and the state of this
dynamical system is specified by two angles and two angular
velocities. Because there is no friction, the double pendulum is
an example of a Hamiltonian system and energy is conserved. This
EJS model simplifies the system by using equal length arms and
masses. Clicking in the Poincare section sets the initial
conditions of the rotor. The user can examine and modify this
simulation if EJS is installed by right-clicking within the plot
and selecting "Open EJS Model" from the pop-up menu item.
