This page has a simple applet demonstrating equilibrium of three forces in a system consisting of two pulleys and three weights. The user can adjust the weights and the placement of the pulleys. The applet shows the user the appearance of the setup, the angles between the lines that hold the weights, and the parallelogram demonstrating the force vectors.
