Working out force from distance object is displace (2D)

  1. Feb 23, 2016 #1
    This is a followup for my project which has been on a previous forum post: https://www.physicsforums.com/threads/wind-tunnel-measurements.856773/

    I'm now trying to work out the forces on the object when under the influence of a 2.5m/s air speed and also knowing the mass of the object. My wind tunnel has the object, wing in this case, hanging from the top with elastic. The next video shows the forces I predict the wing to have.



    Using a square grid (graph paper) behind the object I will take a picture of the location of the wing then turn the air flow on and take a second picture (with the camera in the same place). I predict that V1 and V2 will be of opposite signs (- and +) because of its shape.

    I'm wondering if firstly this is at all possible and secondly the equations I could use to work out the forces labeled in the diagram.

    Yes, you can apply static equilibrium to find the force of H.
    You'll need to know the mass and COG location for the wing.
