Two full turns of the circular scale of a screw gauge cover a distance of on its main scale. The total number of divisions on the circular scale is Further, it is found that the screw gauge has a zero error of While measuring the diameter of a thin wire, a student notes the main scale reading of and. the number of circular scale divisions in line with the main scale as The diameter of the wire is

A screw gauge with a pitch of and a circular scale with divisions is used to measure the thickness of a thin sheet of aluminium. Before starting the measurement, it is found that when the two jaws of the screw gauge are brought in contact, the division coincides with the main scale line and that the zero of the main scale is barely visible. What is the thickness of the sheet if the main scale reading is and the division coincides with the main scale line?
