The circular scale of a micrometer has `200` divisions and pitch of `2 mm`. Find the measured value of thickness of a thin sheet.
.

A

`3.41 mm`

B

`6.41 mm`

C

`3.46 mm`

D

`3.51 mm`

Text Solution

Verified by Experts

The correct Answer is:
B
Least count `= ("pitch")/("No. of divisions")=(2)/(200)=0.01mm`, Reading `= 3 xx 2+(46-5)(0.01)=4.41mm`.

The circular scale of a screw gauge has 200 divisions. When it is given 4 complete rotations, it moves through 2mm . The least count of the screw gauge is

A screw gauge with a pitch of 0.5 mm and a circular scale with 50 division is used to measure the thickness of a thin sheet of aluminium. Before starting the measurement, it is found that when the two jaws of the screw are brought in constant, 45th division coincides with the main scale line and that the zero of main scale line and that the zero of main scale is barely visible. What is the thickness of the sheet, if the main scale reading is 0.5 mm and 25th division coincides with the main scalel line ?

A screw gauge with a pitch of 0.5mm and a circular scale with 50 divisions is used to measure the thicknes of a thin sheet of Aluminium. Before starting the measurement, it is found that wen the jaws of the screw gauge are brought in cintact, the 45^(th) division coincide with the main scale line and the zero of the main scale is barely visible. what is the thickness of the sheet if the main scale readind is 0.5 mm and the 25th division coincide with the main scale line?

The pitch and the number of divisions, on the circular scale, for a given screw gauge are 0.5 mm and 100 respectively without any object, the zero of its circular scale lies 3 divisions below the mean line. The readings of the main scale and the circular scale, for a thin sheet, are 5.5 mm and 48 respectively, the thickness of this sheet is :
