Question

inertia about an axis passing through the center of mass, m is the total mass of the object, and I is the moment of inertia about another axis, parallel to the one for which I_cm is calculated and located a distance d from the center of mass. In this problem you will show that the theorem does indeed work for at least one object: a dumbbell of length 2r made of two small spheres of mass m each connected by a light rod (see the figure). Which moment of inertia equals 4.64 mr^2? I_B I_C I_D I_E Axis X, not shown in the diagram is parallel to the axes shown. It is known that I_X = 6 mr^2. Which of the following is a possible location for axis X? between axes A and C between axes C and D between axes D and E to the right of axis E
