hi i have a lab due and i cant figure this out. we have to find the mass of a paper clip using the net torque equations. we have 3 clamps attached to the fulcrum stand so we have to incorporate the force of gravity on them too. to make the stand level the paper clip attached to a clamp is at 50 cm to the left from the middle and a 20 g mass attached to a clamp is 23 cm to the rigt fro the middle. The last clamp is in the middle. any help i know the mass is supposed to come out around 2 g.
