The pitch of a screw gauge is 1 mm and there are \({100}\text{divisions}\) on circular scale. When faces \({A}\) and \({B}\) are just touching each without putting anything between the studs 32nd divisions of the circular scale (below its Zero) coincides with the reference line. When a glass plate is placed between the studs, the linear scale reads 4 divisions and the circular reads 16 divisions. Find the thickness of the glass plate. Zero of linnear scale is not hidden from circular scale when A and B touches each other.
