Question: 1 / 400

Which part of a micrometer measures whole units in a reading?

The thimble section

The sleeve section

The sleeve section of a micrometer is responsible for measuring whole units in a reading. It serves as the primary scale against which the measurements are taken. The sleeve typically displays the main units of measurement (such as millimeters or inches) and is calibrated to represent whole values.

Other components like the thimble and the rotating vernier scale provide precision measurements to refine the reading beyond the whole units indicated by the sleeve. The thimble allows for fine adjustments to measure fractions of a unit, while the vernier scale enhances accuracy by enabling users to read measurements more precisely. However, the sleeve is the foundational part that indicates the whole measurement, making it key to understanding the overall measurement value on the micrometer.
