Quick Answer: The Force Table is a circular table marked in degrees, with adjustable pulleys on the rim, a central ring, strings and weight hangers, for studying vector addition and the equilibrium of concurrent forces. It is used to verify the parallelogram, triangle and polygon laws of forces and Lami’s theorem.

About This Product
Strings tied to the central ring pass over pulleys set at chosen angles, and weights hung from the free ends pull the ring in different directions. When the ring rests at the centre the forces are in equilibrium, and students record the weights and angles to calculate the resultant and compare it with theory.
Frequently Asked Questions
Which laws can be verified on the Force Table?
