Help with Torque Problem

  1. Nov 28, 2013 #1
    1. The problem statement, all variables and given/known data

    Find the moment (vector) of the force acting on the “L-shaped”
    bracket about the axis indicated.

    2. Relevant equations

    m=rf

    3. The attempt at a solution

    Hypotenuse of triangle = sqrt(13)

    Moment = sqrt(13)* 5 nm


    This is a wrong according to my textbook however I do not understand why.

    The 5.0 N force is not acting perpendicular to the moment arm. Review the definition of how to calculate a moment.

    The moment is a cross product, you haven't taken into account the angle between the moment arm and the force.
