State the formula for determining a pitch
Advertisements
उत्तर
Pitch = `"Unit of main scale"/"No. of divisions in the unit"`
For example: If one-centimetre length has ten divisions then
Pitch = `(1"cm")/10` = 0.1 cm

How can the least count of a screw gauge be decreased?
Which part of vernier callipers is used to measure the internal length of a hollow cylinder?
Figure shows a screw gauge in which circular scale has 100 divisions. Calculate the least count and the diameter of a wire.
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 is the least count in the case of the following instrument?
Metre scale
Define the least count of an instrument.
The following diagrams (Fig. 5) show the use of a vernier caliper under three different situations. Study the diagrams carefully and note down the vernier readings in each case.
