Question

Uniform increase in temperature of, ΔT introduces initial _____

(a) Normal strain

(b) Strain

(c) Stresses

(d) Kinetic energy

The question was asked in an internship interview.

The above asked question is from Finite Element Modelling in portion Axis Symmetric Solids Subjected to Axis Symmetric Loading of Finite Element Method

Answer 1

Correct option is (a) Normal strain

To explain: Strain, is a term used to measure the deformation or extension of a body that is subjected to a force or set of forces. The strain of a body is generally defined as the change in length divided by the initial length. The elongation of the bar is assumed normal, or perpendicular, to the cross section. Therefore, like stress, the strain is called a normal strain.
