State the purpose of ratchet in a screw gauge.
When does a vernier callipers has the negative error?
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?
Sleeve cylinder
How do you account for positive zero error for calculating the correct diameter of wires?
How do you account for negative zero error, for calculating the correct diameter of wires?
Consider the following case where the zero of vernier scale and the zero of the main scale are clearly seen. If L.C. of the vernier calipers is 0.01 cm, write the zero error and zero correction of the following.
