Question

100%

A sheet metal working company purchased a shearing machine from a surplus dealer without
a flywheel. It is calculated that a machine will use 2380 joule of energy to shear a 1.2 mm thick
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 180 rpm and slows down to 160 rpm during the shearing
process. If the arms and hub will account for 12% of the rim weight concentrated at the mean
diameter and that the material density is 0.26 lb/in®, determine the thickness of the rim.
Select one:
O a. 5.19 cm
O b. 4.14 cm
O c. 2.14 cm
O d. 3.13 cm
