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.

Which of the following statement(s) is/are true about the ribs of an airplane wing with semi-monocoque construction?

Your answerSelect all correct options. You can choose more than one.

For a rectangular planform wing, the dimensions of the ribs DO NOT depend on their spanwise position in the wing.

Ribs increase the column buckling stress of longitudinal stiffeners connected to them.

Ribs increase plate buckling stress of the skin panels.

Ribs help in maintaining aerodynamic shape of the wing.
