    1. The problem statement, all variables and given/known data

    Hi I have to calculate the moment of inertia for a thick-walled T profile

    2. Relevant equations



    3. The attempt at a solution

    I have determined the center of gravity (the easy part) of it already how should I proceed?

    Thanks Pep
