The turning moment diagram for a multi-cylinder engine has been drawn to a scale of 1 mm = 4500 N-m 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 mm2, when the engine is running at 160 r.p.m. 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.

Question
The turning moment diagram for a multi-cylinder engine has been drawn to a scale of 1 mm
= 4500 N-m 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 mm2, when the engine is running at 160 r.p.m. 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.
