Three uniform thin rods, each of length L = 16 cm, form an inverted U. The vertical rods each have mass of 14 g; the horizontal rod has mass of 50 g. Where is the center of mass of the assembly (x, y)?
14 at y = 0 and 28 at y = 8 , total mass = 42
14 * 0 + 28* 8 = Ycg * 42
solve for Ycg
Xcg is in the middle of course
