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

Using a screw gauge the diameter was measured. The readings are given belwo: 0.39 mm, 0.38 mm, 0.39 mm, 0.41 mm, 0.38 mm, 0.37 m, 0.40 mm,0.39 mm. Calculate (i) the most accurate value of the diameter (ii) the relative error and (iii) percentage error.

When a screw gauge of least count 0.01 mm is used to measure the diameter of a wire, the reading on the sleeve is found to be 1 mm and the reading on the thimble is found to be 27 divisions.What is the diameter of the wire in cm ?

The pitch of a screw gauge is 1 mm and there are 100 divisions on the circular scale. In measuring the diameter of a sphere there are six divisions on the linear scale and forty divisions on circular scale coincide with the reference line. Find the diameter of the sphere.

A screw gauge gives the following reading when used to mesure the diametre of a wire. Main scale reading : 0 mm Circular scale reading : 52 divisions Given that 1 mm on main scale corresponds to 100 divisions of the circular scale. the diameter of wire from the above data is :
