Question #170748

A double acting steam engine runs at 210 rpm. A curve of turning moment plotted on the crank angle base showed the following areas alternatively above and below the mean turning moment line: 880,500,620,720,360,560,440,520mm2

The scales used where 1mm= 520Nm and 1mm= 1o crank angle. If the total fluctuation in speed is limited to 1.85% of the ,mean speed, determine the mass of flywheel necessary if the radius gyration is 1.4m
