The arms of a Porter governor are 17.8 cm long and are hinged at a distance of 3.8 cm from the axis of the governor. Mass of each ball is 1.15 kg and mass of sleeve is 20 kg. The governor sleeve begins to rise at 280 rpm when the links are at an angle of 30° to the vertical. Determine the friction force on the governor sleeve (a) 10 N (c) 206 N (b) 21 N (d) 15 N The arms of a Porter governor are 17.8 cm long and are hinged at a distance of 3.8 cm from the axis of the governor.
