Circular moment of inertia formula
WebRotational inertia is given the symbol I I. For a single body such as the tennis ball of mass m m (shown in Figure 1), rotating at radius r r from the axis of rotation the rotational inertia is I = mr^2 I = mr2 and consequently … WebOur task is to calculate the moment of inertia about this axis. We orient the axes so that the z -axis is the axis of rotation and the x -axis passes through the length of the rod, as shown in the figure. This is a convenient choice because we can then integrate along the x -axis.
