Question 7 of 10

7. Determine the corrections or otherwise of the following assertion [A] and reason [R]:
Assertion [A]: To generate new airfoil, we use spanwise line instead of chord line in flat wrap interpolation technique.
Reason[R]: Chordwise line will generate flat structure from curves having different values of tangent angle.

Both [A] and [R] are true but [R] is not the correct reason for [A]

Both [A] and [R] are true and [R] is the correct reason for [A]

Both [A] and [R] are false

[A] is true but [R] is false
