Calculate the centroid of the above structure. The key to this process is to break the structure down into simple geometric shapes. Essentially, our structure is a composite body and we are finding the centroid of a composite body by finding the centroids of the subcomponents of the composite body. 1 1.12 1.29 84 R1.00 .50 3.50 2.18 1.50 -.50 .90 .50 2.00 6.25 7.25 -1.00 -1.00 -.50 .50 .50 1.50 .50 1.50 1.00 40 1.50 .50 3.90
