Expert Answer
Figure shows a small rod of length 10.6 mm is measured using a vernier calipers. As shown in figure, there are two scales in vernier caliper.
They are (i) Main scale and (2) Vernier scale.
Smallest division in main scale is 1 mm . In the vernier caliper shown in figure, 20 vernier scale divisions coincide with 19 main scale division.
1 vernier scale division = (19/20) main scale division.
Smallest measurement that can be made by vernier caliper which is known as least count is the
difference between one main scale division and vernier scale division.
Hence smallest measurement or least count = 1 - (19/20) mm = 1/20 mm .
To measure the length of rod, the rod should be hold between two jaws of vernier caliper as shown in figure.
Then we should note down the main scale reading ( MSR ) and vernier scale reading (VSR ).
Let MSR = 10 and VSR = 12
Length = MSR + ( VSR * LeastCount ) = 10 + ( 12 * (1/20) ) = 10.6 mm
