Sir,
while finding the pitch of a Scre Gauge.............what if we stated exactly from
zero on the Main Scale and after fve rtations......the Main Scale reads 5.4mm
or
smthng like that............

then is the pitch 1mm or [5.4/5] mm..................Please reply....

In a screw gauge, the pitch is defined as the distance travelled in one rotation.

Distance travelled in 5 rotations = 5,4 mm

Hence distance travelled in 1 rotation = 5.4/5 = 1.08 mm

Hence the pitch = 1.08 mm

Pitch=No.of divisions uncovered on the pitch scale/No.of rotations given.

Got it?
