= 1. Location of the center of mass. A structure is made up of three-point masses, m1 1 kg, m2 2 kg and m3 = 3 kg, connected rigidly by massless rods. At the moment of interest, the coordinates of the three masses are (1.25 m, 3 m), (2 m, 2 m), and (0.75 m, 0.5 m), respectively. Find the center of gravity of the connected piece. y m3 m2
