... massPdistributed in it. To calculate it, we split the object into very small parts of mass δmi . Then: I = i δmi ri2 where ri is the distance between the piece i and the axis of rotation. I’ve drawn these distances for two such pieces. Finally, let δfi be the force acting on piece i. Clearly, not al ...
