State the purpose of ratchet in a screw gauge.
Which of the following measures a small length to high accuracy : metre rule , vernier callipers or screw gauge?
Define the term 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.
How do you account for positive zero error for calculating the correct diameter of wires?
State whether the following statement is true or false by writing T/F against it.
The ratchet of a screw gauge is used to measure the depth of a beaker.
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.
Thickness of a cricket ball is measured by ______.
Least count of a vernier caliper is ______ cm.
