I am currently studying Rotational Equilibrium and Dynamics in Physics. Our class was given a competitive lab project for extra credit, where the group with the lowest margin of error would win. It is set up as following: You will be given a meter stick and one weight (approximate value of .1kg, but this will be measured for absolute accuracy). You are to calculate the weight of the meter stick. (Correct weight - Your weight)/Correct weight will be used to determine margin of error. I thought about this pretty much all day with my partner and decided to come here for help. To determine the weight of the meterstick, we will need to suspend the weight from a fixed point (axis), but wouldn't we need a support force acting in the opposite direction? Any starting points on how to solve this problem would be helpful.
