Question
State the formula for calculating length if:
Number of vernier scale division coinciding with the main scale and number of division of main scale on the left-hand side of zero of vernier scale is known.
Solution
If we know the number of vernier scale divisions (V.S.D.) coinciding with the main scale and a number of main scale divisions (M.S.D.) on the left-hand side of zero of vernier scale then Length recorded = Main scale reading + L.C. × V.S.D.
