Homework Help: Magnitude of torque

  1. Mar 20, 2009 #1
    The problem statement, all variables and given/known data

    The wrench in the figure has six forces of equal magnitude acting on it. Rank these forces (A through F) on the basis of the magnitude of the torque they apply to the wrench, measured about an axis centered on the bolt. Rank from largest to smallest.

    The attempt at a solution

    I've tried from largest: D, (B, E) (A, F), C

    where bracket up means same rank.

    Force C is along the axis of wrench so its torque is zero, am i right?

    Or the ranking cannot be determined cos we don't know the angles between the r and F ?
