Question

Quizplus · Accepted Answer

The pressure differential across a wing cross section is a result of the difference in air flow velocities. This is explained by Bernoulli's equation, which states that as the velocity of a fluid (in this case, air) increases, the pressure exerted by the fluid decreases. This principle helps explain how wings generate lift.
