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

In a complete rotation, spindle of a screw gauge advances by (1)/(2)mm . There are 50 divisions on circular scale. The main scale has (1)/(2)mm marks to (is graduated to (1)/(2)mm ) If a wire is put between the jaws, 3 main scale divisions are clearly visible, and 20th division of circular scale coincides with reference line. Find diameter of wire in correct significant figures.

A screw gauge has least count of 0.01 mm and there are 50 divisions in its circular scale: The pitch of the screw gauge is:

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.

Circular scale divisions of a screw gauge is 50. Five full rotations advances circular scale by 5mm. Statement 1- Least count of screw gauge is 0.001 cm least count = pitch/(total number of divisions)

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

Accuracy of screw gauge can be increased by …………. The number of divisions on circular scale.
