A Q21. Below are four identical figure L's, which are constructed from two rods of equal lengths and masses. For each figure, a different axis of rotation is indicated by the small circle with the dot inside, which indicates an axis that is perpendicular to the plane of the L's. The axis of rotation is located either at the center or one end of a rod for each figure. Rank these L 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. (C, ABD; parallel axis theorem; use I for rods)
