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

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?
