In a Vernier calliper, each 1 cm on the main scale is divided into 8 equal divisions and 5 divisions of the Vernier scale coincide with 4 divisions on the main scale. What is the Vernier constant of the Calliper?
Answers
Explanation:
Consider a Vernier calipers in which each 1 cm on the main scale is divided into 8 equal divisions and a screw gauge with 100 divisions on its circular scale. In the Vernier callipers, 5 divisions of the Vernier scale coincide with 4 divisions on the main scale and in the screw gauge, one complete rotation of the circular scale moves it by two divisions on the linear scale. Then:

Answer :-
Vernier caliper is a measuring device used to measure readings with a high level of accuracy. Similarly, a screw gauge is also a measuring device used to make accurate measurements of small readings (less than 1 mm or nearly in that range usually). The only major difference between the two measuring devices is that the screw gauge is used only for measuring external measurements, while the vernier caliper is used for both internal as well as external measurements. The visual representation of both these is as follows (the first image is vernier caliper & the second image is screw gauge)
