Question

I the distribution of the change in temperature ΔT, the strain due to this change is ____

(a) Constant strain

(b) Stress

(c) Initial strain

(d) Uniform strain

I got this question in a national level competition.

My question is taken from Two Dimensional Problems in division Two Dimensional Problems using Constant Strain Triangles of Finite Element Method

Answer 1

Right answer is (c) Initial strain

To explain I would say: The amount of heat transferred is directly proportional to the temperature change. The distribution of change in temperature, the strain due to this change is initial strain.
