Q1: The arms of a Porter governor are 250 mm long. The upper arms are pivoted on
the axis of revolution, but the lower arms are attached to a sleeve at a distance of 50
mm from the axis of rotation. The weight on the sleeve is 600 N and the weight of
each ball is 80 N. Determine the equilibrium speed when the radius of rotation of the
balls is 150 mm. If the friction is equivalent to a load of 25 N at the sleeve, determine
the range of speed for this position.
Q2: In a loaded Proell governor shown in Figure below each ball weighs 3 kg and
the central sleeve weighs 25 kg. The arms are of 200 mm length and pivoted about
axis displaced from the central axis of rotation by 38.5 mm, y=238 mm, x=303.5
mm, CE 85 mm, MD 142.5 mm. Determine the equilibrium speed.
