Explain the terms : Pitch .
How are they determined?
Draw a neat and labelled diagram of a screw gauge.
Name its main parts and state their functions.
Name the instrument which has the least count
0.1 mm
What is the need for measuring length with vernier callipers?
A micrometre screw gauge has a negative zero error of 7 divisions. While measuring the diameter of a wire the reading on the main scale is 2 divisions and 79th circular scale division coincides with baseline.
If the number of divisions on the main scale is 10 to a centimetre and circular scale has 100 divisions, calculate
- pitch
- observed diameter
- least count
- corrected diameter.
How the backlash error is avoided?
State whether true or false. If false, correct the statement.
With the help of vernier caliper we can have an accuracy of 0.1 mm and with screw gauge we can have an accuracy of 0.01 mm.
