Problem
The pitch of a screw gauge is 1 mm and there are 50 divisions on its cap. When nothing is placed between the studs, the 44th division of the circular scale coincides with the reference line and the zero of the main scale is not visible; that is, the zero of the circular scale lies above the reference line. When a glass plate is placed between the studs, the main scale reads three divisions and the circular scale reads 26 divisions. Calculate the thickness of the plate.
