WebSep 7, 2024 · The steps to finding a centroid using the composite parts method are: Break the overall shape into simpler parts. Collect the areas and centroid coordinates, and. Apply (7.5.1) to combine to find the coordinates of the centroid of the original shape. As a simple example, consider the L-shaped area shown, which has been divided into two rectangles. WebThe first moment of area assumes that if all the masses, forces, and other reacting physics quantities are acting on the centroid, their total value would be zero. Again, the first moment of area is sometimes called the …
