Answer 51

Relative Wind

Question 52

Bottom part of an airfoil

Answer 52

Lower Camber

Question 53

states that areas with highpressure moves to areas with low pressure. Since the wing is in between the low and high pressures, it is therefore lifted up.

Answer 53

Pressure gradient force

Question 54

This states that, “as the velocity of fluid (air) increases, its internal pressure decreases”

Answer 54

Bernoulli’s Principle (The Venturi Effect)

Question 55

Due to the shape of the airfoil, the air travelling at the top of the airfoil will increase in speed which results in a lower pressure as compared to the pressure below the airfoil. This imbalance is called _______

Answer 55

pressure gradient force.

Question 56

This change in pressure happens due to expansion and compression of fluids.

Answer 56

Bernoulli’s Principle (The Venturi Effect)

Question 57

As air flows around a wing, the air gets deflected downward which results it in lifting (opposite reaction) the wing

Answer 57

Newton’s Third Law of Motion

Question 58

Engineer’s Formula L= CL (1/2)(ρ)(V2)(S) L= Lift CL=Coefficient of Lift ρ = air density V = velocity of the aircraft S = Surface area of the Wing
