AEd IB = Icm + Submit Request AnswerPart D Using the definition of moment of inertia, calculate Ic, the moment of inertia about an axis through point C, for this object. Point C is located a distance r from the center of mass (see the figure). Express your answer in terms of m and r. View Available Hint(s) VO AEd O ? Ic = SubmitPart E Now express Ic for this object using the parallel-axis theorem. Express your answer in terms of m and r. DA O ? Ic = Icm + Submit Request Answer Consider an irregular object of mass m. Its moment of inertia measured with respect to axis A (parallel to the plane of the page), which passes through the center of mass (see the second diagram), is given by IA = 0.64mrs . Axes B, C, D, and E are parallel to axis A; their separations from axis A are shown in the diagram. (Figure 2) In the subsequent questions, the subscript indicates the axis with respect to which the moment of inertia is measured: for instance, Ic is the moment of inertia about axis C
