In structural mechanics, which option is not correct about linear analysis?

(a) Displacements are infinitesimally small

(b) Material is linearly elastic

(c) Externally applied loads are a function of time

(d) Applied loads are not a function of time

This question was posed to me by my college director while I was bunking the class.

The question is from Eigen Value and Time Dependent Problems topic in section Single Variable Problems of Finite Element Method

Best answer

The correct answer is (c) Externally applied loads are a function of time

Best explanation: In a linear analysis, we assume that the displacements of a finite element assemblage are infinitesimally small and the material is linearly elastic. In addition, we also assume that a nature of boundary conditions remains unchanged during application of loads on Finite element assemblage. Loads are constant with respect to time.
