Diagrams show readings of a screw gauge. Figure (i) shows the zero error reading when the screw gauge is closed, figure (ii) the reading when the screw gauge is being used to measure the diameter of a ball-bearing. What is the diameter of the ball-earing ? There are 50 divisions on circular scale.

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 50 divisions on its circular scale. The circular scale is 4 units ahead of the pitch scale marking , prior to use. Upon one complete ratation of the circular scale, a displacement of 0.5 mm is noticed on the pitch scale . The nautre of zero error involved , and the least count of the screw gauge, are respectively.

A screw gauge advances by 3mm in 6 rotations. There are 50 divisions on circular scale. Find least count of screw gauge
