Chapter 6, Problem 6.22P

Interpretation Introduction

Interpretation:

The formula of the stress and strain for a sample is to be written for the tensile test and assume this sample is experiencing necking.

Concept introduction:

Concept of stress and strain will be used. The mathematically expression of stress and strain is given below, respectively-

$\sigma =\frac{F}{A}$

$\epsilon =\frac{\Delta l}{l}$
