What Are the Uses of a Force Table?

A force table is a round apparatus with 360 degrees marked on its surface. A ring in the middle can be manipulated by applying force in the form of a string attached to a weight that pulls it, representing a vector. As more strings and vector force is applied, the effects on the ring in the center can be measured and static equilibrium - the state when the sum of all vector forces is equal to zero - can be achieved by manipulating the various weights.
