Wind tunnel problems

I need help with my prject. Im supposed to figure out how does wing design and force affect lift. Where could I put the wings so that I could measure lift, then put a spring scale somewhere to measure the force?
If you want a picture just ask me and ill send some to you on email

Historically, this has been done in a wind tunnel. The Wright brothers were among the first to come up with a simple wind tunnel balance system to measure these forces accurately. See http://www.first-to-fly.com/Adventure/W ... tunnel.htm and http://www.stkate.edu/physics/Flight/Wr ... elLab.html.

Do you have already have access to a wind tunnel?

yes i do have access to a wind tunnel its just that I need to know where i could put the wings so that I could measure lift and force with a spring scale.

Did you take a look at the picture of the Wright lift and drift balance in the first link? I think you will find most of everything you need in that link.

The Wright lift and drift measurement apparatus was a wire frame that they balanced with no wind. The spring scale and clinometer was used to measure the changes when wind was added.
