The turning moment diagram for a multicylinder engine has been drawn to a scale of 1 mm = 4500 Nm vertically and 1 mm = 2.4 horizontally. The intercepted areas between output torque curve and mean resistance line taken in order from one end are 342, 23, 245, 303, 115, 232, 227, 164 mm, when the engine is running at 150 rpm. If the mass of the flywheel is 1000 kg and the total fluctuation of speed does not exceed 3% of the mean speed, find the minimum value of the radius of gyration.
