2. The figure below shows the load torque profile of a rotating machine operating at an average spread of 1500 rpin. (a) Determine the who of the constant drive torque necessary to move the machine's shaft at this spoil. (b) Determine the mus of a solid disk flywheel required to Emit the speed Huctuations to 0.5 of the nominal speed. Consider the maximum outer diameter available to fit the flywheel in the machine by 1.0 m (c) If the flywheel is maule of steel (density 7000 kg/m ), what would the thickness of the flywheel be? (d) Conskler a rim-typo flywheel with the same 10 m diameter was used (with all the muss on the rim). What would the mass of the llywbool het () Compare results and discuss
