Description
A projection force table, suitable for use on an overhead projector, allows for the visual demonstration of vector addition of forces. By attaching spring scales and weights to a central ring, the setup allows for the adjustment of angles and magnitudes of the forces. The resulting equilibrium condition, where the sum of forces equals zero, is projected, providing a clear and educational visual of how forces combine and balance in two dimensions.
