Moments -- Balancing a weighted meter stick A meter stick is found to balance at the 49.2cm mark when placed on a fulcrum. When a 46.0g mass is attached at the 14.7cm mark, the fulcrum must be moved to the 38.7cm mark for balance. What is the mass of the meter stick? I know I have to use moments but I don't know where to start. Any help would be appreciated.
