Q2. In a spring loaded governor of the Hartnell type, the mass of each ball is 5 kg and the lift of the sleeve is 50 mm. The speed at which the governor begins to float is 240 rpm, and at this speed the radius of the ball path is 110 mm. The mean working speed of the governor is 20 times the range of speed when friction is neglected. If the lengths of ball and roller arm of the bell crank lever are 120 mm and 100 mm respectively. If the distance between the center of pivot of bell crank lever and axis of governor spindle is 140 mm, determine the initial compression of the spring. If friction is equivalent to a force of 30N at the sleeve. *
