Question

1. the amount of excess load that can be imposed on the wing of an airplane depends upon the

oa. position of the cg.
ob. speed of the airplane.
oc. abruptness at which the load is applied.

Explanation:

The amount of excess load on an airplane wing is related to the speed of the airplane. According to aerodynamic principles, higher speeds can lead to greater aerodynamic forces on the wing, which in turn can result in higher excess loads. The position of the CG (center of gravity) mainly affects the stability and balance of the aircraft rather than the excess load on the wing. The abruptness of load application is more about the nature of the load event itself but the primary factor related to the magnitude of the excess load that can be imposed (in a normal flight - related context considering aerodynamic forces) is the speed.

Answer:

B. speed of the airplane.
