Find the moment of inertia of an A × A × A cube with mass M, for the following axes of rotation: (a) An axis through the midpoints of two opposing sides. (b) An axis along one of the edges of the cube.
An object consists of two thin rods, AB with mass M and length 2L, and CD, of mass 2M and length L, joined together at right angles at their midpoints to form a cross. Let E be the point where the two rods intersect. Find the moment of inertia of the
A uniform lamina consists of a disc with radius R with a disc of radius r cut off from its centre, with r < R. The total mass of the object is M. Find the moment of inertia when the lamina rotates about an axis perpendicular to the lamina, thought its
