Question

Bernoulli's principle can be used to explain the lift force on an airplane wing. How must an airplane's wing be designed to ensure that Bernoulli's principle is applicable? Bernoulli's principle can be used to explain the lift force on an airplane wing. How must an airplane's wing be designed to ensure that Bernoulli's principle is applicable? A. Airplane wings must be designed to ensure that air molecules move more rapidly past the bottom surface of the wing, creating a region of higher pressure. B Airplane wings must be designed to ensure that air molecules are deflected upward after hitting the wing. C Airplane wings must be designed so that they are thick enough to ensure a significant pressure difference between the top and bottom surfaces of the wings. D Airplane wings must be designed to ensure that air molecules move more rapidly over the top surface of the wing, creating a region of lower pressure. E Airplane wings must be designed to ensure that air molecules are deflected downward after hitting the wing.

Answer 1

D Airplane wings must be designed to ensure that air molecules move more rapidly over the top surface of the wing, creating a region of lower pressure.


Explanation : Bernoulli's principle works on the idea that as a wing passes through the air the its shape make the air travel more over the top of the wing than beneath it. This creates a higher pressure are beneath the wing than above it. The pressure difference cause the wing to push upwards and lift is created.
Also, more the velocity...lower will be the pressure as per Bernoulli Principle...
