1. The problem statement, all variables and given/known data How do I find Rotational inertia of this?http://yfrog.com/e4asdfasdfasdfj. Assumed thin rod (ignore r). 2. Relevant equations I=1/12 M L2 3. The attempt at a solution Cause that equation applies if the rotation axis is at the center, so I doubled d (and got like (2d)2 and (4d)2) and used the equation, but I ended up with something like 5/3Md2, but the answer at the back says its 8/3Md2.
