MCQ
Applications of Bernoulli's theorem can be seen in:
- ADynamic lift of airplane.
- BHydraulic press.
- CHelicopter.
- DNone of the above.
✓
Answer
- Dynamic lift of airplane.
Explanation:
According to Bernoulli's theorem, when airplane moves, the air streams are created on upper and lower faces of the wings of aeroplane. The velocity of air stream on the upper face is more than that on the lower face. According to Bernoulli's theorem, the pressure is more on lower face than on upper face of the wings of aeroplane. This provides a lift on the aeroplane.
