This week you have learned, or will learn, in physics and chemistry classes about centers of mass and moments of inertia, their meaning and importance. Now we will study how to use calculus to compute these things. In engineering class you will be doing parallel computations in AutoCad.

So here, d=0.6 for an axis through the centroid and parallel to the x axis. To get from that axis to the xx axis itself you need to use the

Centre of Gravity Centre of Gravity (C.G.) is that point through which the resultant of a system of parallel forces formed by the weights of all particles of the body passes. In other words, the point through which the whole weight of the body acts is known as centre of gravity… The moment of inertia about an axis perpendicular to the movement of the rigid system and through the center of mass is known as the polar moment of inertia. Specifically, it is the second moment of mass with respect to the orthogonal distance from an axis (or pole).
