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

A solid consists of a cylinder and a hemisphere of equal radius fixed base to base. Find theratio of the radius to the height of the cylinder, so that the solid has its centre of gravity atthe common face. Hint. For stable equilibrium, the centre of the body should be below the common face ormaximum lie on it. So take the centre of gravity of the body at a distance (a) from thebottom of the hemisphere.
