Daily Quiz # 13e Moment of Inertia V

Course

Shown below (in a top view with the gravitation force into the page Å ) 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 which is in the plane of the page is indicated by the dotted line. The

axes are either at the center or one end of a rod.

Rank these T figures according to the magnitude of the initial angular acceleration 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 initial angular acceleration. _____

Please carefully explain your reasoning.
