The incorrect difference between airfoil and wings is_______

Lift slope of the wing is higher than of airfoil

Difference in the lift-curve slope

Presence of induced drag in wings

Different effective angles of attack seen by

Correct Answer : Lift slope of the wing is higher than of airfoil

Explanation : The finite wing has a lower lift slope than infinite wing (airfoil). This is another difference than the presence of induced drag between wings and airfoil. Also, the effective angles of attack are different for both, being the same only when the lift is zero (at zero lift angle of attack).

Is loading distribution is represented by the sum of finite number?

True

False

Can Not Say

None of the above

Correct Answer : Option (A) : True

Explanation : In the collocation solution of the basic integral equation, the loading distribution is represented by the sum of a finite number of known functions with unknown coefficient substituting the loading representation into their result.

Is it difficult to predict the analytically overall amount of lift?

True

False

Can Not Say

None of the above

Correct Answer : Option (A) : True

Explanation : It is difficult to predict analytically the overall amount of lift that a wing of given geometry will generate. The lifting line theory yields the lift distribution along the span wise direction based only on the wing geometry and flow conditions.

Is prandtl lifting line theory is a mathematical model that predicts lift distribution over a three-dimensional wing?

True

False

Can Not Say

None of the above

Correct Answer : Option (A) : True

Explanation : The prandtl lifting line theory is a mathematical models that predicts lift distribution over a three dimensional wing based on its geometry. It is also known as the lanchester-prandtl wing theory. It was used to calculate lift on the wing.
