Question

The lift distribution goes to zero at the tips for the finite wings.

(a) False

(b) True

(c) Only true for elliptical wings

(d) Only true for rectangular wing

This question was addressed to me in an interview for job.

Asked question is from The Vortex Filament, the Biot-Savart Law, Helmholtz Theorem topic in division Flow over Airfoils over Finite Wing of Aerodynamics

Answer 1

Correct option is (b) True

For explanation I would say: For a finite wing, there is pressure equilibrium from the bottom to the top of the wing, which makes the lift at the tips zero. This is true for all wing shapes.
