Q3/ A Porter governor has equal arms of 250 mm length each and pivoted on the axis of rotation. Each ball is of 50 N weight and the weight of the central load is 250 N. The radius of rotation of the ball is 150 mm when the governor begins to rise and 200 mm when the governor is at maximum speed. Find the range of speed, sleeve lift, when the friction at the sleeve is neglected.
