· This is also known as the geometric centre, or first moment of area.
· The fundamental definition for Centroids is given below, although a more efficient method for problems with simple geometries is discussed later.
· When finding centroids, look for symmetry, the centroids will be in the center of symmetrical sections.
· A simple example of application for these relationships is given below,
· Lets try a more practical problem using the centroid, ([Hibbeler, 1992], prob. 9-16, pg. )
