The profile of aeroplane wing which lifts it up is called as_____________?
Correct answer: B. Aerofoil profile
- A. Wing shape
- B. Aerofoil profile
- C. Curved profile
- D. None of these
Explanation
An aerofoil has a specially shaped cross-section that makes air move differently over its upper and lower surfaces, producing a pressure difference and lift. The technical name for this cross-sectional shape is an aerofoil profile, not merely a wing shape.

About Bernoulli's Equation
Bernoulli’s equation applies conservation of energy to steady flow of an incompressible, non-viscous fluid along a streamline: pressure, kinetic and gravitational terms have a constant total. It explains pressure-speed changes in narrow pipes, Venturi meters and lift, and differs from continuity because it relates pressure as well as velocity and height.
