Principle of superposition is applicable when

Answer & Solution
Correct Answer: Option A
The principle of superposition is applicable when the deflections in a structure are linear functions of the applied forces.

This principle holds when the relationship between force and displacement is directly proportional, meaning that the total displacement caused by multiple forces is the sum of the displacements due to each force acting individually.

For this to be valid, the material must behave elastically and within its linear range, which is often governed by Hooke's law.

Option B is correct

Option A is wrong
because it is the displacement not the deformation which is linear function of applied forces.

Correct me if iam wrong
