This applet demonstrates equilibrium of three forces in a system consisting of two pulleys and three weights connected by strings. The user can change 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.
This applet is part of a collection of applets available in a wide range of languages.
Please note that this resource requires
at least version 1.4.2 of Java.
