# How to Calculate and Solve for Extension | Hooke’s Law

Last Updated on December 20, 2022

The image above represents extension.

To compute for extension, two essential parameters are needed and these parameters are Elastic Constant (k) and Force (F).

The formula for calculating extension:

e = F/k

Where:

e = Extension
F = Force
k = Elastic Constant

Let’s solve an example;
Given that the force is 18 and the elastic constant is 2. Find the extension?

This implies that;

F = Force = 18
k = Elastic Constant = 2

e = F/k
e = 18 / 2
e = 9

Therefore, the extension is 9 m.

Nickzom Calculator – The Calculator Encyclopedia is capable of calculating the extension.

To get the answer and workings of the extension using the Nickzom Calculator – The Calculator Encyclopedia. First, you need to obtain the app.

You can get this app via any of these means:

You can also try the demo version via https://www.nickzom.org/calculator

Apple (Paid) – https://itunes.apple.com/us/app/nickzom-calculator/id1331162702?mt=8
Once, you have obtained the calculator encyclopedia app, proceed to the Calculator Map, then click on Materials and Metallurgical under Engineering.

Now, Click on Mechanical Properties under Materials and Metallurgical

Now, Click on Hooke’s Law under Mechanical Properties

Now, Click on Extension under Hooke’s Law

The screenshot below displays the page or activity to enter your values, to get the answer for the extension according to the respective parameter which is the Elastic Constant (k) and Force (F).

Now, enter the values appropriately and accordingly for the parameters as required by the Elastic Constant (k) is 18 and Force (F) is 2.

Finally, Click on Calculate

As you can see from the screenshot above, Nickzom Calculator– The Calculator Encyclopedia solves for the extension and presents the formula, workings and steps too.
