Homework Help: Moment direction

  1. Nov 15, 2011 #1
    1. The problem statement, all variables and given/known data

    Moment turns in clockwise direction, indicated with arrow. Two dimensional problem.

    2. Relevant equations

    RHR.

    3. The attempt at a solution

    Right hand rule.


    My issue is that I've been taught that the moment "goes out of the board" or "into the board", however this is a 2d problem. If I have a picture of the moment going in a clockwise direction flat on the page, how could I determine what direction my F and r are? Also, would this moment be in the x, y, or both?
