i was given a lab to find the mass of a meter stick using only a lever. Here's what the writeup says: Problem: Find the mass of a meter stick. (No cheaters, no scales!) Materials: Fulcrum, a 100 g mass, a mass hanger of mass 16.5 g, fulcrum pivot, meter stick. Procedure: You are completely on your own to come up with on this one. (Hint: Remember that the mass of the meter stick acts like it comes completely from the center of gravity.) Not exactly sure where to start with this one, though i think that you need to use torque. Any help will be appriciated, Thanks.
