the least count of the main scale of a screw gauge is 1 mm. the minimum number of divisions on its circular scale required to measure 5`mu m` diameter of a wire is :

A screw gauge of pitch 1.0 mm has 200 divisions on its circular scale. Find out its least count.

Pitch of a screw gauge is 0.5 mm and its least count is .01 mm, Calculate no. of divisons on its circular scale.

Two full turns of the circular scale of a screw gauge cover a distance of 1 mm on its main scale. The total number of divisions on the circular scale is 50. Further it is found that the screw gauge has a zero error of -0.03 mm. While measuring the diameter of a thin wire, a student notes the main scale reading of 3 mm and the number of circular scale division in line with the main scale as 35. The diameter of the wire is

Two full turns of the circular scale of a screw gauge cover a distance of 1 mm on its main scale . The total number of divisions on the circular scale is 50. Further more it is found that the screw gauge has a zero error of - 0.02 mm .
