The mass moment of inertia (mmi) of a flywheel (large disc) attached to the main (c) shaft of a rock crushing machine the machine maintain a continuous crushing force. the designer of the machine has determined that a mmi of 100 kg. m2 is required. the fly wheel is to be made of cast iron with a density of 7210 kg/m2. if the thickness (axial length) of the flywheel is limited to 0.25 m, what is the minimum flywheel radius needed to provide the required mmi? a symbolic solution is required initially. work in base si units state the units for your answer.
