The rotating masses per cylinder are equivalent to 100 kg at the crank pin, and the reciprocating masses per cylinder to 200 kg. The wheel centre lines are 2 m apart. The cranks are at right angles.

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. The friction force for both cases is 10 N.

The distances of the centers from the axis of rotation are 20 mm, 30 mm, and 20 mm and their angular positions are 120 degree apart. Find the amount of out-of-balance force and couple at 600 rpm. If the shaft is balances by adding two masses at a radius of 70 mm and at a distance of 100 mm from the central plane of the middle eccentrics, find the amount of masses and their angular positions.
