Diagonal scale
Diagonal scale is an engineering measuring instrument which is composed of a set of parallel straight lines which are obliquely crossed by another set of straight lines. Diagonal scales are used to measure small fractions of the unit of measurement.[1]
Etymology
Diagonal scale is derived from the Latin word Diagonalis. The Latin word was originally coined from the Greek word diagōnios where dia means "through" and gonios denotes "corners".[1][2]
Principle of Diagonal scale
Diagonal scale follows the principle of similar triangles where a short length is divided into number of parts in which sides are proportional.[3]
Application
Diagonal scale is used in engineering to read lengths with higher accuarcy as it represents a unit into three different multiple in metres, centimeters and millimeters.[4] Diagonal scale is an important part in Engineering drawings.[5]
