The image above represents engineering strain. To calculate engineering strain, two essential parameters are needed and these parameters are **Extension (e)Â **andÂ **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

So, Strain = 20 / 5

Strain = 4

Therefore, theÂ **engineering strainÂ **is **4.**

**Calculating the Extension when the Engineering Strain and the Length are 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

Then, e = 2 x 8

e = 16

Therefore, theÂ **extensionÂ **isÂ **16.**

**Calculating the Length when the Engineering Strain and the Extension are 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}

Then, l = ^{44} / _{4}

l = 11

Therefore, theÂ **lengthÂ **isÂ **11.**
