Question Statement:
Consider the four basic symmetrical flight loading conditions corresponding to the
corners of a typical V-n diagram. For one of these flight loading conditions, it is
observed that (i) the compressive bending stresses have a maximum value in the
bottom aft region (see figure) of the wing cross-section; and (ii) the tensile
bending stresses are maximum in the upper forward region (see figure) of the
wing cross-section. For the preceding observations, select the corresponding flight
loading condition from the options given.
Options:
- (A) Positive high angle of attack
- (B) Positive low angle of attack
- (C) Negative high angle of attack
- (D) Negative low angle of attack
