Aerodynamics -- Wind tunnel I'm not sure if this goes under here since it's not actually homework but it's more of a general question for a paper I have to do, so if it's in the wrong place I apologize; simply tell me and I'll delete it or something. Okay well for my research paper I'm thinking of doing how the design of aircraft wings affect lift. I'm planning on constructing a simple wind tunnel but assuming I get everything else to work, I'm not exactly sure how to measure lift inside the wind tunnel. If someone could be of help, it would greatly be appreciated. Thanks.
