I was using a airfoil in a wind tunnel in school to find out drag and Co-efficient of drag.. anyway. Drag was given from the computer and i need to calculate the coefficient. I found that i need the surface area. I have the dimensions of the wing im using. They are 19.5cm x 10.3. So do i just multiply those, or do i also multiply by 2 to account for the top and bottom. Or is the surface area when calculating Cd just one side. thanks

None of the above. Look at your wing in the same direction the wind was blowing. Look at the total width of the sample tested and its height and calculate the area of its silhouette. The length dimension front to back is irrelevant.

The problem with your whole argument is it is based on a premise that everyone is able to become wealthy, and immediately, and there are never any downfalls. A safety net is not there for people who are irresponsible. It is there for people who our economic system fails, for the time being. Capitalism creates poverty. Some one must be poor in a capitalist system, or the system fails. Everyone cannot be rich, or the system will not work. And in this period currently, there is 1 job for every 5 applicants. So how are people irresponsible, when there aren't enough jobs? Really, who is irresponsible? If we are saying the government doesn't create jobs, the private sector does, are they not responsible right now? Your argument is BS. Also, Republicans do not have the same philosophy towards social issues and economic issues, as you stated. They don't have "socioeconomic ideas" because their ideas are opposite on those. I know you were trying to sound smart, sorry it didn't work out for you.
