The above concept can be extended to obtain the moment of inertia of semicircular and quarter circular area as given below. Fig.8.5 Moment of inertia of : (a) semicircle, and (b) quarter circle WebAnalogously, we can define the tensor of inertia about point O, by writing equation(4) in matrix form. Thus, we have H O = [I O] ω , where the components of [I O] are the moments and products of inertia about point O given above. It follows from the definition of the products of inertia, that the tensors of inertia are always symmetric. The Webmoment of inertia of the disc about its center? Well, we can think of the disc as being made up of a bunch of thin rings. We can “add up” the moments of inertia of all the rings using calculus, and the result will be the moment of inertia of the disc. Let’s see how this works.
