In a screw gauge the graduation in the circular scale consists of 100 equal divisions and 10 complete rotation of the cap is equivalent to 5 mm on the main scale While measuring diameter of a wire with screw gauge a particular observation gives initial circular cap reading as 57 and after completing 3 complete rotation the final circular cap reading as 63 It is observed that while proceeding from initial reading to final reading the cap reading increases Calculate the diameter of the wire from the above data
