Knowing the location of the centroid or the center of gravity of the simpler shaped part, we can easily determine the location of the points for the more complex composite body. EXAMPLE 1 EXAMPLE 1 Determine the location of the centroid Determine the location of the centroid of the cross section of the cross section SOLUTION 1 SOLUTION 1 Separate the cross section into three segments : 1 2 3 Calculate the area and the moment of the area for each segment: ( 29 in 2 48 96 = = = A A y y Segment Area, in....
