(20%) Problem 5: A frequently quoted rule of thumb in aircraft design is that wings should produce about 1000 N of lift per square meter of wing. (The fact that a wing has a top and bottom surface does not double its area.) > A 50% Part (a) At takeoff, an aircraft travels at 67 m/s, so that the air speed relative to the bottom of the wing is 67 m/s. Given the sea level density of air to be...
