Figure is a simplified sketch of the mecha- nism used to raise the bucket of a bulldozer. The bucket and its contents weigh 10 kN and have a center of gravity at H. Arm ABCD has a weight of 2 kN and a center of grav- ity at B; arm DEFG has a weight of 1 kN and a center of gravity at E. The weight of the hydraulic cylinders can be ignored. Calculate the force in the horizontal cylinders CJ and El and all forces acting on arm DEFG for the position shown. 30°1, 30° 0.6 m 0.9 m 0.6 m 0.9 m 0.6 m 0.9 m 0.3 m
