Question

The pitch of the screw of a screw gauge that advances 5 mm for 5 complete rotations of its head is ________.

• A. 1 mm
• B. 2 mm
• C. 3 mm
• D. 4 mm

Answer 1

The correct option is A 1 mm

In $5$ complete rotations, the screw of the screw gauge advances $5mm$. Pitch is defined as the distance by which the screw advances in one complete rotation.

Thus pitch, $P=\frac{5mm}{5}=1mm$
