Question

how to find the reading of micrometer screw gauge​

Answer 1

Answer:

You can use a mircometer to measure small (>2.5 cm) diameters that can fit within the 'jaws' of the screw-gauge can be measured to within a hundredth of a millimeter. Close the jaws of the micrometer and check for a zero error. Place the wire between the anvil and spindle end as indicated in the diagram.

kindly mark my answer is the brainliest if possible and if you think so.

Answer 2

Answer:

Steps to be taken for getting the correct reading are:

Find the zero error of the screw gauge, Z.

Note the main scale reading(M) and the circular scale reading (C). Hence, the reading is M+Cp where p is the least count.

Adjust for zero error.
