A sheet metal working company purchase a shearing machine from a surplus dealer without a flywheel. It is calculated that the machine will use 238 Joules of energy to shear a 1.2 mm thick sheet metal. The flywheel to be used will have a mean diameter of 91.44 cm with a width of 25.4 cm. The normal operating speed is 3 rps and slows down to 160 rpm during the shearing process. Assuming that the arms and the hub will account for 12% of the rim weight concentrated at the mean diameter and that the material density is 0.26 Ib/cu.in, compute for the weight of the flywheel.
