To Calculate: The magnitude of drag force,
Answer to Problem 66GP
Explanation of Solution
Given:
The thrust force of the engine,
The mass of the aircraft,
Formula used:
Let the drag force is acting x distance above the centre of mass (CM) of aircraft.
From the equilibrium condition in x & y -direction:
Calculation:
Substituting the given values:
From equation (1) & (2):
Substitute the value of drag force and lift force in equation (3):
Conclusion:
The drag force is equal to the thrust force of the engine and is acting 2.6 m above the centre of mass (CM) of aircraft.
