Question

to measure diameter of a given wire and thick mass of a given sheet using screw guage​

Answer 1

Answer:

Find the value of one linear scale division (L.S.D).

Determine and record the pitch and least count of the screw gauge.

To find the zero error, bring the plane face B and A near. ...

Move face B away from face A. ...

Linear scale reading (L.S.R) is recorded by noting down the no. ...

Let n be the no.of divisions of the circular scale lying on the reference line.

To measure diameter in a perpendicular direction, repeat steps 5 and 6 by rotating the wire to 90°.

For the entire length of wire, repeat steps 4,5,6 and 7 for five different positions and record the observations.

Find the total reading and also zero correction.

Take the mean of different values of diameter.

Using a half-meter scale, measure the length of the wire. Repeat this step three times and record the readings.
