Question

Lab 8 Assignment: Moment of Inertia 1) Moment of Inertia for Different Systems The resistance to rotational motion change is more involved than for linear motion because it not only depends on what the mass is, but also on how that mass is distributed about the axis of rotation. The farther away from the axis the mass is distributed, the greater the moment of inertia. Using this simple definition, for each of the following pairs of objects, determine which of the following has the higher moment of inertia or whether they have equal moments of inertia (write in the space below each figure). (Don't look in your book or use any equations!). m m m m m m M M
