How to use engineering scale?

Answer 1

more info please, I don't know if you mean length scale or weight scale.

Or even voltage, current, temperature, any one of hundreds of scales.

.

Answer 2

An engineer's scale is a tool for measuring distances and transferring measurements at a fixed ratio of length. It is commonly made of plastic and is just over 300 mm (twelve inches) long, so that the measuring ticks at the edges do not become unusable by wear. It is used in making engineering drawings, commonly called blueprints, in scale. For example, "one-tenth size" would appear on a drawing to indicate a part larger than the paper itself. It is not to be used to measure machined parts to see if they meet specifications.

In scientific and engineering terminology, a device to measure linear distance and create proportional linear measurements is called a scale. A device for drawing straight lines is a ruler. In common usage both are referred to as a ruler.

In Canada and the United States, this scale is divided into decimalized fractions of an inch, but has a cross-section like an equilateral triangle, which enables the scale to have six edges indexed for measurement. One edge is divided into tenths of an inch, and the subsequent ones are directly marked for twentieths, thirtieths, fortieths, fiftieths, and finally sixtieths of an inch.

On a metric engineer's scale, common scales are 1:100, 1:200, 1:250, 1:300, 1:400, and 1:500.

Answer 3

I am not sure there is a single type of "engineering scale".  Describe the different edges and maybe we can help.

Answer 4

this question is missing a small part which is the question itself , which eng. scale u are asking about , we have got many
