A multi-cylinder engine is to run at a speed of 600 r.p.m. On drawing the crank-effort diagram to scale of 1 cm 2452.5 N-m and I cm 30°, the areas above and below the mean torque line in sq.cm. are as follows: +1.6, -1.72, +1.68, -1.91, +1.97 and -1.62. The speed is to be kept within ±1% of the mean speed of the engine. Calculate the necessary moment of inertia of the flywheel. Determine the suitable dimensions of a rectangular flywheel rim, if the breadth is twice the thickness. The density of the cost- iron is 725 gm/cm' and its hoop stress is 588.6 N/cm2. Assume that the rim contributes 92% of the flywheel effect.
