A screw gauge gives the following readings when used to measure the diameter of a wire.
Main Scale Reading: 0mm
Circular scale reading: 52 divisions
Given that 1mm on main scale corresponds to 100 divisons on the circular scale. The diameter of the wire from the above data is

A

0.026 cm

B

0.26cm

C

0.052cm

D

0.52cm

Text Solution

Verified by Experts

The correct Answer is:
C
Diameter D = MSR + (CSR + LC)
`= 0 + 1//100xx 52 = 0.52mm = 0.052cm`

The pitch of a screw gauge is 1mm and its cap is divided into 100 divisions. When this screw gauge is used to measure the diameter of a wire, then main scale reading is 2 mm and 58^(th) division of circular scale coincides with the main scale. There is no zero error in the screw gage. Then the diameter of the wire is

A screw gauge with a pitch of 1 mm has 100 divisions on its circular scale. What it is used to measure the diameter of a thin wire, the main scale reading is 3 mm and the circular scale reading is 45. If D is the diameter of the wire in mm, then find the value of D.

The pitch of a screw gauge is a mm and there are 100 division on the circular scale. While measuring the diameter of a wire, the linear scale reads 1mm and 47th division on circular scale coincides with the reference line. The length of the wire is 5.6 cm. Find the curved surface area (in cm^2) of the wire in proper significant figures.
