Linear Scale Vs. Non-Linear Scale

I will be discussing linear and non-linear scale in this post. I will also provide examples of both scales.

What is a linear scale? A linear scale is a scale that consists of equally space divisions, sections or proportions. What does that mean? Well it mean that each line, grid or marking you see are equal in value or size. You can think of the divisions, sections or proportions on a linear scale has being directly proportional. Linear scale is used to obtain accurate measurement of distance, mass, volume, etc. Machines also utilize linear scale to produce the desire outputs.

Some machines that utilize linear scale includes; drilling machines, lathe, milling machines, and planer. There are hundreds of other machines that utilize linear scale. Examples of linear scale includes; ruler, measuring tape, measuring cylinder, graph sheet, etc.

We will now look at non-linear scale. As the name suggest “non-linear”, which mean uneven or not equal. So a non-linear scale consists of unequally space divisions, sections or proportions. This mean that the lines, grids or markings you see are not equal or constant in value or size. Or scientifically speaking the divisions, sections or proportions are not directly proportional. If you want a really good example of a non-linear scale take a look at the logarithmic scale.

In Graph A the relationship between distance and time is linear. Why? You can say each meter is covered in the same time throughout the journey. E.g. 1meter = 2 seconds, 2m = 4sec, 3m = 6sec, etc. In Graph B the relationship between distance and time is non-linear. Why? You can say each meter is not cover in the same time throughout the journey. E.g. 1m = 2sec, 2m = 5sec, 3m = 13sec, etc.

I hope you find this post helpful.

One response to “Linear Vs. Non-Linear Scale

  1. Thanks for the article, but I noticed that the image is showing the linear and nonlinear relationship but its doesn’t show the linear and nonlinear scales which is the article subject, because both graphs above are for linear scale but showing constant speed for the first and varying speed for the second.
