Which of the following is NOT a purpose of using dividers in fitting operations?
Measuring the thickness of plates
The nature of a tool defines its purposes, and dividers are a marking tool with two straight, sharply pointed legs set to a distance rather than a graduated measuring instrument.
Because the legs can be locked at a set opening, dividers are used to transfer a distance taken from a rule onto the workpiece accurately.
With one point as a centre, the other point scribes circles and arcs on a marked-out surface, which is a routine layout use.
By stepping the set opening along a line, dividers also divide that line into a number of equal parts.
All these uses involve setting and scribing distances, but the legs carry no scale or jaws, so dividers cannot read a value such as the thickness of a plate.
Measuring plate thickness needs a graduated jaw instrument like a vernier caliper or micrometer, so that is the task dividers are not meant to perform.
Hence, the answer is Measuring the thickness of plates.
