A multi-cylinder engine is to run at a constant load with an average speed of 600 rpm. The magnitude of the areas above and below the mean torque line are as follows: +2096, -2253.2, +2200.8, -2502.1, +2580.7, -2122.2 The speed fluctuation is 2% and moment of inertia of the machine is 60 kg.m² a) Calculate the necessary moment of inertia of the flywheel. b) The maximum and minimum speed throughout a cycle a) Determine suitable dimensions for cast iron flywheel. The density of cast iron is 7250 kg/m³, and its mass is 143.5 kg.
