True or False, Parallel Axis Theorum

  1. Nov 22, 2013 #1
    1. The problem statement, all variables and given/known data

    I am doing an assignment where I have this (easy) true/false question.

    The parallel axis theorem can be used to find moments of inertia of an object about arbitrary axes, provided the moment of inertia about a perpendicular axis through the centroid of the object is known.

    2. Relevant equations

    T=rf

    3. The attempt at a solution

    Ok, by definition this is true. And from what I understand this is what the parallel axis theorem does. I am reviewing the concept in my textbook.

    But I only have one try for this.. it would be great if I could get some re-enforcement for my answer!

    Is a "parallel axis" the same as an "arbitrary axis"?

    Well I read "perpendicular" as "particular" - you have to watch those.
    That was probably the one you were supposed to notice.
