(C) Finding Equilibrium from Two Unknown Masses You will now be given three angles and one mass, and asked to find the other two masses. As before, at the beginning of the lab the mass of a typical nut was given, along with its uncertainty. When you make your measurements you should assess their actual precisions through the normal means. Object # 1 Mass Unknown – find Angle 120° Unknown - find 210° 3 6 nuts 0°
