The screw gauge which I m talkin bout (image attached) has a circular scale and a main scale. By main scale division I mean the distance between two marks on a main scale.
In a screw gauge, the pitch is defined as the distance traveled in one rotation. Is it also equal to the length of one main scale division?
If the length of one main scale division is not given, then can we take it to be equal to the pitch? Or do we take it as equal to some other default value.
