What do you mean by zero error of a screw gauge? How is it accounted for?
Name the instrument which can accurately measure the following
The internal diameter of the neck of a water bottle
Who invented vernier callipers?
A micrometre screw gauge has a negative zero error of 8 divisions. While measuring the diameter of a wire the reading on the main scale is 3 divisions and the 24th circular scale division coincides with baseline.
If the number of divisions on the main scale are 20 to a centimetre and circular scale has 50 divisions, calculate
- pitch
- observed diameter.
- least count
- corrected diameter.
How do you account for negative zero error, for calculating the correct diameter of wires?
What is the least count in the case of the following instrument?
vernier calipers
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.
