Purpose: Demonstrate that equilibrium of forces is an insufficient condition for static equilibrium
Description: The weight of the rod is balanced, with the rod held in a horizontal position, using two equal weights hung over pulleys. While holding the rod fixed, move a small weight from one side to the other. The force condition for equilibrium is still met, but the torque condition is not the same, and the rod will rotate.
