The skid loader shown has a mass of 1.28 Mg and in the position shown the center of mass is at G. There is a 255 kg barrel in the bucket with its center of mass at GB.
The horizontal distance between the barrel's center of mass and the front wheels is d = 1.33 m.
The horizontal distance between the front wheels and rear wheels is w = 0.55 m.
The bucket arm is held horizontal between D and E and the pair of hydraulic cylinders creates angle /EDC of 0 = 32 degrees.
