Problem 8 on Hartnell governor spring loaded governor

In a spring loaded governor of the Hartnell type, the mass of each ball is 5 kg and the lift of sleeve is 50 mm. The speed at which governor begins to float is 240 rpm and at this speed the radius of ball path is 110 mm. The mean working speed of governor is 20 times the range of speed when friction is neglected. If the length of ball and roller arm of the bell crank lever are 120 mm and 100 mm respectively and if the distance between the centre of pivot of the bell crank lever and axis of governor spindle is 140 mm, determine the initial compression of the spring taking into account obliquity of arms. If the friction is equivalent to a force of 30 N at the sleeve, find the total alternation in speed before the sleeve begins to move from mid position.
