Question

What is meant by a backlash error in a screw gauge?

Answer 1

1. Screw gauge: It is a simple device that is used to measure very short lengths (even 10^-6 m or 0.01mm) accurately,
2. For example, the thickness of the paper, hair, etc.
3. The backlash error is an error that happens when the screw may not move forward even when the screw head is being rotated.
4. The backlash error may occur due to the fast rotation of the screw or due to the wear and tear of different parts of the screw gauge.
