Explain Vernier caliper, micrometre and height gauge working principles and least count ?

Question

Accepted Answer

Vernier caliper, micrometre and height gauge are measuring tools used in engineering.

Vernier caliper measures length, width, and depth of an object with high accuracy. Its least count is 0.02 mm.
Micrometre measures thickness, diameter, and depth of an object with high precision. Its least count is 0.01 mm.
Height gauge measures the height of an object with high accuracy. Its least count is 0.02 mm.
All three tools work on the principle of linear measurement and have a sliding scale that moves along a fixed scale.
The least count is the smallest measurement that can be read on the scale of the tool.
