Tension & Torque, Static Equilibrium

  1. Apr 8, 2013 #1
    1. The problem statement, all variables and given/known data

    2. Relevant equations

    [itex]Ʃτ = 0[/itex]
    [itex]τ = rFsinθ[/itex]

    3. The attempt at a solution

    I'm not even really sure where to start with this. My first thought was that it's not moving, so presumably the forces sum to 0. I also thought of treating the point where the net is exerting force as a point of rotation, but that doesn't make much sense.

    There's an unknown force you don't care about: the force of the ground on the pole. So you want to take moments about a point for which that force will have no moment. What point is that?
