Procedure to find the location of the centroid of a three-dimensional volume and to find the center of mass of a volume of non-uniform density, by taking the first moment integral.
Procedure to find the location of the centroid/center of mass of a shape by the Method of Composite Parts: breaking the shape down into simpler components for individual analysis.
Procedure for finding a body's area moments of inertia through integration, used to determine the body's resistance to bending (second area moments) or resistance to torsion (polar moment of inertia).
