Q6. A Porter governor has arms of equal length and three flyweights each of mass 5 kg. The central mass is 24 kg and friction at the sleeve is constant at 18 N if the central mass moves.

When running at a steady state speed the governor height is 116 mm.

Calculate EACH of the following:

(a) The steady state speed of the governor in rev/min, assuming no friction is acting;

(b) The speed in rev/min at which the governor will start to move from the steady state speed if the speed is increasing, including the effect of friction;

(c) The speed in rev/min at which the governor will start to move from the steady state speed if the speed is decreasing, including the effect of friction.
