Question
Explain the term pitch. How are they determined?
✓
Answer
When one complete rotation is given to the screw hand, it moves forward or backward by a distance called the pitch of the screw. It is a distance between two consecutive threads of the screw.
Pitch of the screw = distance travelled by screw-in n rotations/n rotations
Pitch of the screw = distance travelled by screw-in n rotations/n rotations
