The diameter of a wire as measured by a screw gauge of pitch 0.5 mm is 8.3 mm. The pitch scale reading is:
The pitch of a screw gauge is 1 mm and there are 100 division on the circular scale. A students measures a diameter of a wire using this screw gauge and he gets main scale reading as 5 mm and circular divisions as 25. If the screw gauge has positive zero error 0.03mm, the correct value of diameter will be
When a screw gauge with a least count of 0.01 mm is used to measure the diameter of a wire, the reading on the pitch scale is found to be 0.5 mm and the reading on the head scale is 27 divisions. If the zero error is +0.005 cm, what is the diameter of the wire?
