Analyze the double pendulum motion with this application. The Double Pendulum model displays the motion of a double pendulum and its Poincare map. A double pendulum is a 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 fiction, 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.?A Cash-Karp fifth order ODE solver is used to compute the motion.

The Double Pendulum model was created using the Easy Java Simulations (EJS) modeling tool. It is distributed as a ready-to-run (compiled) Java archive. Double clicking the ejs_lagrangian_DoublePendulum.jar file will run the program if Java is installed. EJS is a part of the Open Source Physics Project and is designed to make it easier to access, modify, and generate computer models.
