State one use of a screw gauge.
State the purpose of ratchet in a screw gauge.
The pitch of a screw gauge is 0.5 mm and the head scale is divided in 100 parts. What is the least count of a screw gauge?
Is it possible to increase the degree of accuracy by mathematical manipulations? Support your answer by an example.
The circular scale of a screw gauge has 50 divisions. Its spindle moves by 2 mm on the sleeve, when given four complete rotations calculate
- pitch
- least count
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 do you account for positive zero error for calculating the correct diameter of wires?
Name the measuring employed to measure the diameter of a pencil.
What is the least count in the case of the following instrument?
vernier calipers
How will you find the Zero Error of Vernier Caliper? Explain.
