उत्तर
Vernier caliper is an instrument used for measuring small lengths of solid objects where an ordinary scale cannot be applied. We can measure the length accurately up to the order of 10-2 cm, 10-3 cm depending upon the vernier used. Therefore a vernier caliper is important to measure the fraction of the smallest division of a measuring scale which otherwise could not be done by the judgment of the eye.

Draw a neat and labelled diagram of a screw gauge.
Name its main parts and state their functions.
A micrometre screw gauge having a positive zero error of 5 divisions is used to measure diameter of a wire, when reading on the main scale is 3rd division and the 48th circular scale division coincides with baseline. If the micrometer has 10 divisions to a centimetre on the main scale and 100 divisions on a circular scale, calculate
- Pitch of screw
- Least count of screw
- Observed diameter
- Corrected diameter.
What do you understand by the following term as applied to micrometre screw gauge?
Baseline
What do you understand by the term least count of screw?
The Wavelength of a particular colour is 5400Å. Express it in nanometer and metre.
What do you mean by a negative zero error of a screw gauge? How will you calculate it?
Define the pitch of the screw gauge.
How does negative error arise in the instrument?
How many types of motions does a screw have?
If the 47th division of the circular scale coincides with the zero of the main scale of a screw gauge of least count 0.01 mm and having 50 circular divisions, what is it's zero error?
