The circular scale of a screw gauge has 50. divisions and pitch of 0.5 mm. Main scale reading is 2. Find the diameter of sphere.

A screw gauge has 50 circular scale divisions and a pitch of 0.1 cm. When this is used to measure the thickness of a plate the main scale reading is 0.2 cm and the circular scale reading is 35. What is the thickness of the plate?

The circular scale head of a screw gauge is divided into 200 divisions and move 1 mm ahead in one revolution. The diameter of the wire, when the pitch scale reading shows 6mm (when the wire is firmly held between the studes) and 45^(th) division on circular scale coincides with the reference line.

Distance travelled by linear scale of screw gauge during two full rotation of circular scale is 1mm and circular scale has 50 divisions. In an experiment to measure thickness of a plate, six divisions of main scale are clearly visible and 28^(th) division of circular scale coincides with reference line. Moreover when studs touch each other, zero of circular scale lies 4 division below the reference line, thickness of the plate will be:
