3)Which of the following is more accurate in measuring the dimensions of an object?

4)What is the screw gauge also called?

6)A carpenter, while driving a screw through a wooden block, of thickness 1 cm, observe that he has to rotate the screw 10 times for the purpose. The pitch of the screw is :

7)The part of the screw gauge which prevents it from undue tightening.

Answer 2

1: another name of screw gauge

Ans:- micrometer
=====================================================================
2: what is the principle of screw gauge

Ans:- The line distance moved by the screw is directly proportional to the rotation given to the head .
=====================================================================
3:why is screw Guage so named
Ans:- it is generally used to measure the diameter of wires which are governed
By some standard numbers called standard wire gauge
=====================================================================
4:- what is zero error of the screw gauge
Ans:- when the screw tip is in contact with the stud and the zero line of the head scale does not coincide with the reference line of the pitch scale , there is zero error
=====================================================================
5:- what is the basic functions of a ratchet
Ans:- it prevents the screw being pressed too hard or too soft against the object
=====================================================================
6:- define pitch of a screw gauge
Ans:- the pitch of a screw gauge Is the distance moved by the screw for one complete rotation
