Daily Quiz # 13b Moment of Inertia II

Course

Below are five identical figure T's which are constructed from two rods of equal lengths and

masses. For each figure, a different axis of rotation in the plane of the paper is indicated by the

dotted line. The axis of rotation is located either at the center or one end of a rod for each

figure.

Rank these T figures according to their moments of inertia about the indicated axes, from

largest to smallest. Ignore the width of each rod but not the length.

Largest 1. _____ 2. _____ 3. _____ 4. _____ 5. _____ Smallest

Or, all these T systems have the same moment of inertia. _____

Please carefully explain your reasoning.
