Name the two scales of a vernier callipers and explain how it is used to measure length correct up to 0.01 cm.
State the formula for determining a pitch
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.
What do you understand by the following term as applied to micrometre screw gauge?
Thimble
How do you account for positive zero error for calculating the correct diameter of wires?
How the backlash error is avoided?
The following figure shows the reading of a vernier caliper used for measuring the thickness of a metal sheet.
(i) Find the least count of the instrument.
(ii) Calculate the thickness of the metal sheet.
Least count of a vernier caliper is ______ cm.
