Vernier Scale History, Features, Role in Measuring Distances with Precision from an Instrument
A Vernier scale is a way to get a much better result when measuring how long something is or the size of an angle.
Sometimes when measuring things we need to get our measurement as accurate as possible. Accuracy is important in surveying the land, navigation of ships, making parts for machines like car engines, looking at stars and planets in astronomy and when doing Experiment in science.
A vernier scale is a visual aid that allows the user to measure more precisely than could be done unaided when reading a uniformly-divided straight or circular measurement scale.
In the following, N is the number of divisions the maker wishes to show at a finer level of measure. Direct verniers are the most common.N graduations of the indicating scale cover N−1 graduations of the data scale.
Retrograde verniers are found on some devices, including surveying instruments. A retrograde vernier is similar to the direct vernier, except its graduations are at a slightly larger spacing than on the main scale.
The main use of the vernier calliper is to measure the internal and the external diameters of an object. To measure using a vernier scale.
