Question

v12 indicates that the poisson’s ratio that characterizes the decrease in ______ during tension applied in ______

(a) 2- direction and 1- direction

(b) 2- direction and 3- direction

(c) 1- direction and 2- direction

(d) 2- direction and 4- direction

The question was asked during an online interview.

I need to ask this question from Two Dimensional Problems in section Two Dimensional Problems using Constant Strain Triangles of Finite Element Method

Answer 1

Right answer is (a) 2- direction and 1- direction

For explanation I would say: Poisson’s ratio is the ratio of transverse contraction strain to longitudinal extension strain in the direction of stretching force. Tensile deformation is considered positive and compressive deformation is considered negative.
