z f - Locate the center of mass of the composite body. Materials 1, 2, and 3 have densities of 2.7 Mg/mº, 5.7 Mg/m", and 7.8 Mg/m3, respectively. Use a = 25 mm, b = 20 mm, c = 50 mm, d = 22 mm, e = 80 mm, and f = 75 mm for your calculations. Your Answer: x-coordinate of the center of mass in mm (round the result to the nearest integer): y-coordinate of the center of mass in mm (round the result to the nearest integer): z-coordinate of the center of mass in mm (round the result to the nearest integer):
