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. 1.25 m GB D 60000 A G B E C 0.15 m 0.5 m d W i. Determine the reaction force on the pair of wheels at the front of the skid loader at A. ii. Determine the reaction force on the pair of wheels at the rear of the skid loader at B. iii. Determine the magnitude of the compressive force in a single hydraulic cylinder CD. Note that there are two hydraulic cylinders, one on each side of the skid loader. iv. Determine the magnitude of the reaction force on a single pin that attaches the bucket assembly to the skid loader chassis at E.…
