2D stress states can be suitable for analysis of aircraft structures. a) True b) False

a) True

Explanation:

Yes we can say that 2D stress can be suitable for analysis of aircraft structures. We know that in general in air craft there are four forces these are thrust force, lift force and drag force due to air and force due to its weight.

These all forces acting in one plane so we can say that this is 2D analysis of stress.
