Hey everyone, I'm a student working on building a wind tunnel with some classmates. I'm in charge of figuring out the drag and lift force sensors. I'm currently looking these two components: http://www.jameco.com/webapp/wcs/stores/servlet/Product_10001_10001_2128260_-1 http://www.jameco.com/webapp/wcs/st...1&productId=2136471&catalogId=10001&CID=MERCH I don't really have any experience with either of these, and am not sure if these are suitable for measuring drag and lift (I'd order two, one for each of the types of forces). I'm looking to do something like this setup: http://www.grc.nasa.gov/WWW/k-12/airplane/tunbalint.html I'm also considering this setup from Science Buddies, as shown below. It consists of two Vernier force sensors attached to a vertical pole that mounts a test object in the testing chamber. It seems like a fairly easy and reliable setup, however. I think it requires use of Logger Pro. That will work, but it's not the most flexible--the other types of sensors could be easily programmed with an arduino nano to do whatever we need. Any thoughts or comments are appreciated!
