Yeah I have access to a wind tunnel...
It's not a repost since I've decided now to focus on proving that the drag coefficient of a sphere is 0.5. The only thing I need to think of is an experiment to measure the drag force...but can't come up with one :mad:
Yeah maybe your right sponge is not so good...
"What data do you hope to get from the tunnel? How will you relate those things to a sphere's overall motion? You'll get some drag data, but how are you going to use that data?"
That is my problem since I'm not entirely sure how to get some...
I have to do an investigation about the Aerodynamics of a ball/sphere and I have to look at how changing the velocity and the cross-sectional area of the ball affects it's motion.
I'm planning to build a wind tunnel out of cardboard and put a fan in it to generate the velocity wanted...I've...
