The arms of a Proell governor are 250 mm long. The upper arms are pivoted on the axis of rotation, while the lower arms are pivoted at a radius of 35 mm. Mass of each ball is 5 kg and is fixed to the extension 100 mm long of the lower arms. The central sleeve load is 100 N. At minimum radius of 160 mm the extension to which the balls are attached are parallel to the governor axis. Determine the equilibrium speeds for radii of 160 and 200 mm.
