The pitch of a screw gauge is `1` mm and there are `100` division on its circular scale. When nothing is put in between its jaws, the zero of the circular scale lies `4` divisions below the reference line. When a steel wire is placed between the jaws, two main scale divisions are clearly visible and `67` divisions on the circular scale are observed. the diameter of the wire is

A

`2.71mm`

B

`2.67mm`

C

`2.63mm`

D

`2.65mm`

Text Solution

Verified by Experts

The correct Answer is:
C
`p=1mm,N=100`
Least count `C=P/N=(1mm)/100=0.01mm`
The instrument has a positive zero error
`e=+NC=+4xx0.01=0.04mm`
Main scale reading is `2xx(1mm)=2mm`
Circular scale reading is `67(0.01)=0.67mm`
`:.` observed reading is `R_(0)=2+0.67=2.67mm`
So true reading `=R_(0)-e=2.63mm`

The pitch of a screw gauge is 1 mm and there are 100 divisions on its circular scale. When nothing is put in between its jaws, the zero of the circular scale lies 6 divisions below the reference line. When a wire a placed between the jaws, 2 linear scale divisions are clearly visible while 62 divisions on circular scale coincide with the reference line. Determine the diameter of the wire.

The pitch of a screw gauge having 50 divisions on its circular scale is 1 mm When the two jaws of the screw gauge are in contact with each other, the zero of the circular scale lies 6 divisions below the line of gradution. when a wire is placed between the jaws, 3 linear scale divisions are clearly visible while 31 division on the circular scale coincides with the reference line. Find diameter of the wire.

The pitch of a screw gauge is 1mm and there are 100 divisions on its circular scale. When nothing is put in between the studs and the two studs are in contact as well, the zero of the circular line lies 6 divisions above the reference line. When a thin uniform wire is placed firmly between the two studs, 2 divisions on the pitch scale / linear scale are clearly visible, while 62^(nd) division on the circular scale coincides with the reference line. The diameter of the wire is

The pitch of a screw gauge is 1mm and there are 50 divisions on its cap. When the two studs are firmly in contact, the zero of the circular scale lies 6 divisions below the line of graduation. When a wire is held firmly in between the studs, 3 pitch scale divisions are clearly visible, while 31^(st) division on the circular scale coincide with the reference line. The diameter of the wire is.

The pitch of a screw gauge is 0.5m and there are 50 divisins on its circular scale and one man scale division =0.5mm . Before starting the measurement, it is found that when jaws of the screw gauge are brought in contact, the zero of the circular scale lies 5 divisions above the reference line. When a metallic wire is placed betwen the jaws, four main scale divisions are clearly visible and 16^(th) division on the circular scale coincides with the reference line. The diameter of the wire is

The pitch of a screw gauge is 1 mm and there are 100 "divisions" on circular scale. When faces A and B are just touching each without putting anything between the studs 32nd divisions of the circular scale (below its Zero) coincides with the reference line. When a glass plate is placed between the studs, the linear scale reads 4 divisions and the circular reads 16 divisions. Find the thickness of the glass plate. Zero of linnear scale is not hidden from circular scale when A and B touches each other.

The pitch of a screw gauge is 1 mm and there are 50 divisions on its cap. When nothing is put in between the studs, 44th divisions of the circular scale coincides with the reference line and the line and the zero of the main scale is not visible or zero of circular scale is lying above the reference line. When a glass plate is placed between the studs, the main scale reads three divisions and the circular scale reads 26 divisions. Calculate the thickness of the plate.
