Acceleration with masses = 0.0066 ms-2Acceleration without masses = 0.019 ms-2hanging mass = 0.100 kgDiameter of pulley = 3.3 cm (radius = 0.0165 m)Distance between masses and pivot = 0.20 cmSpinning masses = 0.2714 kgI = mgr2/aIwith = 4.04 x 10-2 kgm2Iwithout= 1.406 x 10-2 kgm2Imasses = 2.67 x 10-2 kgm2Σmr2 = 2.17 x 10-2 kgm2The larger value is consistent with the torque being less than mgr.
