    The pitch of a screw gauge is 0.5 mm and there are 50 divisions on the circular scale. In measuring the thickness of a metal plate, there are five divisions on the pitch scale (or main scale) and thirty fourth divisions coincide with the reference line. Calculate the thickness of the metal plate.

    The pitch of a screw gauge is 0.5mm and there are 50 divisions on its circular scale and one main scale division =0.5 mm. Before starting the measurement it is found that when jaws of the screw gauge are brought in contact, the zero of the circular scale lies 4 division above the reference line. when a metallic wire is placed between the jaws, five main scale divisions are clearly visible and 18^(th) division on the circular scale coincides with the reference line. the diameter of the wire is

    A vernier calipers and a screw gauge have the same least count and zero error with the difference that the vernier calipers has positive zero error and the screw gauge has negative zero error. The number of circular scale divisions on the screw gauge is twice the number of vernier scale divisions on the vernier calipers and the pitch of the screw gauge is 1mm. If the vernier coinciding division and the circular are 3 and 97, respectively then find the number of vernier scale divisions on the vernier calipers.

    The pitch of a screw gauge is 1mm and its cap is divided into 100 divisions. When this screw gauge is used to measure the diameter of a wire, then main scale reading is 2 mm and 58^(th) division of circular scale coincides with the main scale. There is no zero error in the screw gage. Then the diameter of the wire is

    A screw gauge has 1.0mm pitch and 200 divisions on the ciruclar scale. The least count of the instrument is
