The arms of a Porter governor are equal in length and pivot on the axis of rotation. The mass of each ball is 10 kg and the mass of the central load is 25 kg. The ball rotates at radius 210 mm when the governor is at its lowest setting and 260 mm when it is at its maximum setting. At maximum speed, the vertical distance from the center of the sleeve to the pivot was 500 mm. For another case, it can be seen that the height of the governor will reduce to half values when the ball masses are replaced by three-time larger from the first case.
