What is the principal of micrometre

Question

Accepted Answer

The principle of micrometre is to measure small distances or thicknesses with high precision.

Micrometre is a measuring instrument used to measure dimensions in micrometers (µm).
It consists of a stationary anvil and a movable spindle that can be adjusted to measure the distance between them.
The micrometre scale is typically graduated in increments of 0.01 mm or 0.001 mm.
To measure an object, the spindle is brought into contact with one surface while the anvil is in contact with the other surface.
The reading on the micrometre scale indicates the distance between the two surfaces.
Micrometres are commonly used in manufacturing, engineering, and quality control to ensure precise measurements.
For example, a quality inspector may use a micrometre to measure the thickness of a metal sheet or the diameter of a screw.
