Table of centroids
The following is a list of centroids of various two-dimensional and three-dimensional objects. The centroid of an object $${\displaystyle X}$$ in $${\displaystyle n}$$-dimensional space is the intersection of all hyperplanes that divide $${\displaystyle X}$$ into two parts of equal moment about the … See more • List of moments of inertia • List of second moments of area See more • http://www.engineering.com/Library/Artic… WebTables of centroids of common shapes can be used. Because of the additive property of integrals, the centroid of the combination of several basic shapes can be calculated as and where is the centroid of each basic shape and is the area of each corresponding shape. Shapes can also be subtracted by using a negative area.
