How to Calculate and Solve for Engineering Strain | Mechanical Properties

Last Updated on December 20, 2022

The image above represents engineering strain.

To compute for engineering strain, two essential parameters are needed and these parameters are Extension (e) and Length (l).

The formula for calculating engineering strain:

Strain = e/l

Where:

Strain = Engineering Strain
e = Extension
l = Length

Given an example;
Find the engineering strain when the extension is 20 and the length is 5.

This implies that;

e = Extension = 20
l = Length = 5

Strain = e/l
Strain = 20 / 5
Strain = 4

Therefore, the engineering strain is 4.

Calculating the Extension when the Engineering Strain and the Length is Given.

e = Strain x l

Where:

e = Extension
Strain = Engineering Strain
l = Length

Let’s solve an example;
Find the extension when the strain is 2 and the length is 8.

This implies that;

Strain = Engineering Strain = 2
l = Length = 8

e = Strain x l
e = 2 x 8
e = 16

Therefore, the extension is 16.

Calculating the Length when the Engineering Strain and the Extension is Given.

l = e / Strain

Where:

l = Length
Strain = Engineering Strain
e = Extension

Let’s solve an example;
Find the length when the engineering strain is 4 and the extension is 44.

This implies that;

Strain = Engineering Strain = 4
e = Extension = 44

l = e / Strain
l = 44 / 4
l = 11

Therefore, the length is 11.
