Toys for a Torque Weighted Ruler 1. Set up a balanced weighted ruler system with two different known masses suspended in cradles at different positions on the same side of the meter stick, balanced by a third unknown weight, warunk on the other side, keeping the pivot at the center of the ruler. Weigh the hanging scales, clips, and masses. You will use torques to determine the weight of the unknown, Wink....
