A circular plate with radius r = 0.941 m lies next to a rectangular plate with base br = 0.783 m and height hr = 0.898 m which lies next to a triangular, isosceles plate with base bt = 1.51 m and height ht = 0.80 m, see figure. Determine the common center of gravity of the three plates in the x-direction if the plates are the same thickness and are made of the same material.
