This following applet is Double pendulum
Created by prof Hwang Modified by Ahmed
Original project Double pendulum

By the way prof Hwang i would ask this simulation is the same 
When download EJS right by name Users/ntnu/fkh ?
I change size and add code clear Graphic by click using mouse

Embed a running copy of this simulation
<applet code='users.br.ahmed.DoublePendulum_pkg.DoublePendulumApplet.class' archive='http://www.phy.ntnu.edu.tw/ntnujava/ejsuser/37048/ejs_DoublePendulum.jar' name='DoublePendulum6275' id='DoublePendulum6275' width='909' height='439' mayscript=true><param name='draggable' value='true'></applet>
Embed a running copy link(show simulation in a popuped window)
<a href='http://www.phy.ntnu.edu.tw/ntnujava/msg.php?smfejs=6275' target='smfejs'>Run simulation</a>

In mathematics, in the area of dynamical systems, a double pendulum  is a pendulum  with another pendulum attached to its end, and is a simple physical system that exhibits rich dynamic behavior.
The motion of a double pendulum is governed by a set of coupled ordinary differential equations. For certain energies its motion is chaotic.
