The turning moment diagram for a multicylinder engine has been drawn to a scale Imm = 600 N-m vertically and Imm = 3° horizontally. The intercepted areas between the output torque curve and the mean resistance line, taken in order from one end, are as follows: +52, -124, +92, -140, +85, -72 and +107 mm2, when the engine is running at a speed of 600 r.p.m. If the total fluctuation of speed is not to exceed ±7.5% of the mean, find the necessary mass of the flywheel of radius 0.5 m. Find the mass of the flywheel • Ans.: 183 kg
