WebMoments of inertia #rem. The moment of inertia of a body, written IP, ˆa, is measured about a rotation axis through point P in direction ˆa. The moment of inertia expresses how hard it is to produce an angular acceleration of the body about this axis. That is, a body with high moment of inertia resists angular acceleration, so if it is not ... WebFinding the centroid (geometric center) or center of mass for 2D and 3D shapes.
