The length of each arm of a Porter governor is 350 mm. The lower arms are attached to a sleeve at a distance of 25 mm from the axis and the upper arms are pivoted on the axis of rotation. The load on the sleeve is 250 N and the weight of each ball is 25 N. If the radius of rotation of the balls is 125 mm at a speed of 225 rpm, then calculate the following: (i) Speed of governor after the sleeve has lifted 55 mm (ii) Effort (iii) Power of the governor
