Induced drag is generated by a component of lift for a finite wing.(a) True(b) FalseThe question was asked by my college director while I was bunking the class.This interesting question is from Downwash and Induced Drag topic in portion Flow over Airfoils over Finite Wing of Aerodynamics

Answer»

The correct answer is (a) True

Explanation: The local LIFT vector is not aligned perpendicular to the free-stream velocity vector for a wing. Lift is perpendicular to local relative wind. This CAUSES a component of local lift in the direction of drag, CALLED induced drag.
