Summary: Centroid by Composite Body Method The shaded region shown in Figure 3 represents the cross section of a mechanical component with uniform density. The dimensions shown in the figure (given in millimeters) give a complete description of the size and location of every feature. From this information: (a) "Break" the composite body down into parts. Show a clear diagram of each part, including the location of the centroid of each part (x, >) relative to the origin in Figure 2 [18 points] (b) Find X, the distance along the x-axis from the origin to the centroid of the whole composite body using the information you found in part (a). Express your answer in millimeters and make sure it is relative to the origin shown in Figure 2. NOTE: You do not have to find Y for the composite body, just X [12 points] 20 20 80 10 30 X Figure 3 10
