PURPOSE: To demonstrate equilibrium of forces.
DESCRIPTION: Forces are applied by hanging arbitrary weights on hangers over pulleys. The ring to which the forces are applied will stabilize symetrically about the center pin when the forces are in equilibrium. Forces can be applied at arbitrary angles by rotating the pulley arms. Click your mouse on the photograph above to see details of the center of the force table and the system displayed using an overhead projector.
