A linear scale is a line which is divided into equal parts. It is used on maps to show the relationship between a particular distance on a map and the actual distance on the earth. A linear scale is also called a bar scale or graphic scale.

Answer 2

Answer:

• Linear scale is also called bar scale, graphic scale or graphical scale. It is used to visually show the scale of a map, engineering drawing etc. In map layouts a scale bar is a very common element.

• The term bar scale was given by Bowditch in 1962. He was an American Practical Navigator.

• Linear scale is used to measure equal changes in a physical quantity with an instrument with equal distances. We can find the least count of a scale by dividing the distance between two extreme points by number of divisions between them.
• There are two types of divisions on a linear scale: primary and secondary.
• Examples of linear scale are : ruler, measuring tape, thermometer, graph etc.
