38 Bernoulli’s Principle Conceptual Physics Text Correlation: Section 20.8 Question 1 • What if the pressure • Answer: By the wing difference is tiny surface being big! A tiny. How can this lift tiny pressure a plane? difference multiplied by a large wing surface can equal a very big force! Question 2 • How can airplanes • Answer: Planes can fly fly upside down? upside down by ensuring that there is an angle of attack as the plane moves forward. This is done by the fuselage which is tilted so the wings deflect oncoming air downward and not upward. Question 3 • Is a cambered roof • Answer: Yes, for it (one with sloping acts like the airfoil of sides rather then a wing horizontal) more apt to be blown off in strong winds?
