Question

determine the zero error, zero correction, pitch and least count of the given wire taking three sets of readings in perpendicular directions​

Answer 1

Answer:

Aim

To measure diameter of a given wire using screw gauge.

Apparatus

Screw gauge, wire, half-metre scale and magnifying lens.

Theory

1. If with the wire between plane faces A and B, the edge of the cap lies ahead of Mb division of linear scale.

Then, linear scale reading (L.S.R.) = N.

If nth division of circular scale lies over reference line.

Then, circular scale reading (C.S.R.) = n x (L.C.) (L.C. is least count of screw gauge) Total reading (T.R.) = L.S.R. + C.S.R. = N+n x (L.C.).

2. If D be the mean diameter and l be the mean length of the wire,Volume of the wire,
