... Four very tiny spheres are fastened to the corners of a frame of negligible mass lying in the xy plane. (a) If the system rotates about the y axis with an angular speed find the moment of inertia about this axis. (b) Suppose the system rotates in the xy plane about an axis through O (the z axis). Ca ...

... Conservation of Angular Momentum for 2D Rigid Body In subsequent Lectures, we will apply conservation of angular momentum for a general system in three dimensions. However, the dynamics of a 2D rigid body can easily be incorporated into our study of particle motion. We therefore specialize these res ...
