Answer:
Type A, B, and C. Vernier calipers are classified based on an international standard IS 3651-1974, according to this standard three types of vernier calipers have been specified to meet external and internal measurement requirements of up to 2000mm with the accuracy of 0.02, 0.05, and 0.1 mm.
Answer:
A vernier caliper is an instrument which is most commonly used for a variety of exact measurements, which was not necessarily related to the engineering manufacturer.
There are three types of vernier caliper used in the physics laboratory to measure lengths of small objects accurately which could not have been possible with a metre scale.
The main use of the vernier caliper is to measure the internal and external diameters of an object. The word caliper means any instrument with two jaws which is used to determine the diameters of objects.
In ancient China, the caliper was born without the beginning of scale as the Qin Dynasty (AD 9). In 1631, French Pierre Vernier introduced a device to obtain accurate measurements required for scientific experiments.
The principle of the vernier caliper is that when two scales or divisions slightly different in size are used, then the difference between them is used to increase the accuracy measurement.
