A Proell governor has equal arms of length 300 mm. The upper and lower
ends of the arms are pivoted on the axis of the governor. The extension arms of the lower links are
each 80 mm long and parallel to the axis when the radii of rotation of the balls are 150 mm and
200 mm. The mass of each ball is 10 kg and the mass of the central load is 100 kg. Determine the
