Bending Moment on Pole due to Wind

  1. Aug 9, 2011 #1
    Hello Friends.

    I have a question for the following scenario:

    There are two wooden poles, both set into the ground so that they are sticking straight up. The height of Pole One is H1 feet. The height of the Pole 2 is H2 feet. Supported in between these two poles is a wire. The ends of the wire is attached to the top of each pole. The wire has a total length of L and is pretty straight.

    Now imagine that a wind is blowing, exactly perpendicular to the wire. What is the bending moment at the base of Poles 1 and 2 due to this wind blowing on the wire? (Please ignore the bending moment due to wind blowing on the pole surfaces). Assume the wind loading on the conductor is W lbs/foot.

    My idea: I think that if the attachment height at the poles were the same, lets say "H", then the moment at the base of each pole would be: (H)(W)(L)(0.5). But when the attachment heights are different, I don't know how to calculate that! Any help is tremendously appreciated! Thanks!!
