Question

Calculate the diameter of a coin with the help of a vernier calipers which shows main scale reading as 5 and vernier coincidence as 4 with nil zero error​

Answer 1

Answer:

A Vernier caliper is a precision instrument that measures internal dimensions, outside dimensions, and depth. It can measure to an accuracy of one thousandth of an inch and one hundredth of a millimeter. The caliper has two sets of jaws, one each on the upper and lower portions.

Vernier caliper least counts formula is calculated by dividing the smallest reading of the main scale with the total number of divisions of the vernier scale.LC of vernier caliper is the difference between one smallest reading of the main scale and one smallest reading of vernier scale which is 0.1

The least count (LC) is given by LC = 1 MSD - 1 VSD = 1.0 - 0.9 = 0.1 mm. Given, the main scale reading (MSR) is 10 and the Vernier scale reading (VSR) is 1. The measured value of the edge is given by a=MSR+VSR×LC=10+1×0.1=10.1mm.
