Introduction: In this lab, we determined the net force acting on a metal ring by adding the vectors of attached strings and subsequent weights, to find the sum (resultant). Summary: Three strings were attached to a metal ring, which was placed in the middle of a force table. Next, A metal post was inserted through the center of the ring and anchored into the table. Pullys were loosely clamped to the outer edge of the table. Next, the strings were led over the pullys and checked to be sure that the angles they created with each other did not form right angles. Weights of varying sizes were then hung from the strings and pullys were adjusted so that the metal ring was at rest in the center of the table. When at rest, ring was flicked to ensure it would return to center and all masses and angles were recorded along with their uncertainties. Finally, tension was calculated in Newtons, force vectors were added graphically to determine the resultant vector, algebra was
