Answer 2

VERNIER CALIPER

Vernier caliper is used to measure the internal diameter of workpiece.

KEY TAKEAWAYS OF VERNIER CALIPER:

* The vernier calliper was invented in 1631 by Pierre Vernier of France as a tool for obtaining extremely precise linear measurements. It has two graduated scales: a primary scale that looks like a ruler and a specifically graded auxiliary scale called the vernier that glides parallel to the main scale and allows readings to be taken to a fraction of a division on the main scale.

* Vernier scales with 10 divisions of the same length as the main scale are also available; the reading procedure is identical to that described above. A vernier scale can improve the accuracy of both angular and linear measurements.
