Concept explainers
How many newtons of lift are exerted on the wings of an airplane that have a total area of
Force exerted on the wings of airplane.
Answer to Problem 65A
Force exerted on the wings,
Explanation of Solution
Given:
Area of wing,
Difference in air pressure below and above wings is 5% of atmospheric pressure.
Formula Used:
The pressure is given as,
Where,
Calculation:
Since the atmospheric pressure is
So, the pressure on the wing is
Putting the values in formula,
Conclusion:
Therefore, the lift exerted on the wings of an airplane is
