Problem
The pitch of a screw gauge is 1 mm and there are 100 divisions on its circular scale. When nothing is placed between its jaws, the zero of the circular scale lies 6 divisions below the reference line. When a wire is placed between the jaws, 2 linear-scale divisions are clearly visible while 62 divisions on the circular scale coincide with the reference line. Determine the diameter of the wire.
