Define the term 'Vernier constant'.
(a) A vernier scale has 10 divisions. It slides over the main scale, whose pitch is 1.0 mm. If the number of divisions on the left hand of zero of the vernier scale on the main scale is 56 and the 8th vernier scale division coincides with the main scale, calculate the length in centimetres.
(b) If the above instrument has a negative error of 0.07 cm, calculate the corrected length.
Figure shows a screw gauge in which circular scale has 100 divisions. Calculate the least count and the diameter of a wire.
What do you understand by the following term as applied to micrometre screw gauge?
Sleeve scale
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.
How will you measure the least count of vernier caliper?
