Two metal disks are taped to a meterstick. The mass of the
meterstick is 460 grams. Disk 1 has a mass of 300 grams
and is located at the 28 cm mark. Disk 2 has a mass of
500 grams and is located at the 64 cm mark. At what posi-
tion along the meterstick should you place a fulcrum so that
the entire system (meterstick plus the 2 masses) is balanced?

totalmass*cg=mass1*position1 + mass2*position2 + massstick*50cm

solve for cg.
