Question

How can backlash error be avoided?

Answer 1

1. Screw gauge: an instrument that is used to measure very short lengths (even 10^-6 m or 0.01mm) accurately,
2. For instance, the thickness of the paper, hair, etc.
3. The backlash error happens, when the screw may not move forward even when the screw head is being rotated.
4. The backlash error is incurred due to regular use as well as wear and tear or fast movement of the screw.
5. It can be avoided by always rotating the screw slowly only in one direction.
