1. The problem statement, all variables and given/known data I need to rank these masses from greatest to least rotational inertia. We have not been taught integration, so I know we won't be using it. I have a chart of formulas for certain shapes though. I am just not sure if I even need them. 2. Relevant equations I=Mr^2. <-- I dont think I will use this. I know that one thin rod about the perpendicular is I=1/12ML^2. . . but the book does not give one for about the length. . . this leads me to believe that the formulas are not necessary. I think it is sort of a trick question, but I am not sure why. 3. The attempt at a solution Any hints would be great.
