Question

In a certain piece of modern sculpture, four iron spheres are connected in a line by lightweight rods. The separation between each sphere’s geometric center and the next along the line is 50 cm. The spheres decrease in size along the line; their masses are 44kg, 22 kg, 11 kg and 5.5 kg respectively; and their diameters are 22 cm, 17 cm, 14 cm, and 11 cm respectively. The artist wants to suspend this system of spheres by a single wire so that it rotates ponderously in the breeze above the viewers’ heads. We will see in unit N that the appropriate place to attach the wire is at the system’s center of mass. Where is this point (relative to the center of the most massive sphere)?
