Polygon of Forces

| View Cart ⇗ | Info

“In the apparatus shown... three forces act on a small body and are allowed to assume a position of equilibrium. A triangle is then constructed with sides parallel respectively to the three forces; it will be found by measurement that the sides are also the lengths proportional to the forces, and as will be seen the arrowheads point concurrently round the triangle.
