The Moment of Inertia, I, of an Object Is the Second

question 64

Multiple Choice

The moment of inertia, I, of an object is the second moment of its mass distribution relative to an axis of rotation, , where r is the perpendicular distance from the rotation axis and is the density of the object at a distance r from the rotation axis. What is the moment of inertia for rotation about the y-axis of a shape described by the region bordered by x = 0, and y = 0 revolved about the y-axis? Assume the density of the material is 1.0, so that mass and volume will be numerically equivalent. [Hint: Cylindrical shells are particularly conducive to moment-of-inertia calculations since r is everywhere the same for a given shell.]
