In case of a single cylinder double acting steam engine, 180 kW power is being developed at a mean speed of 120 r.p.m. The coefficient of fluctuation of energy is 0.12. The fluctuation of speed is ± 2% of mean speed. The flywheel rim has mean diameter of 2 metre. The hub and spokes of the flywheel provide 8% of the rotational inertia of the flywheel. If the density of the flywheel material is 7200 kg/m3, determine the mass and cross-sectional area of the flywheel rim.

A shaft with 3 meters span between two bearings carries two masses of 10 kg and 20 kg acting at the extremities of the arms 0.45 m and 0.6 m long respectively. The planes in which these masses rotate are 1.2 m and 2.4 m respectively from the left end bearing supporting the shaft. The angle between the arms is 60°. The speed of rotation of the shaft is 200 r.p.m. If the masses are balanced by two counter-masses rotating with the shaft acting at radii of 0.3 m and placed at 0.3 m from each bearing centers, estimate the magnitude of the two balance masses and their orientation with respect to the X-axis, i.e. mass of 10 kg ‎‏Note: It must be solved using the graphic method, not the equations method.
