The circular scale of a screw gauge has `200` divisions. When it is given `4` complete rotations, it moves through `2mm`. The least count of the screw gauge is

Define least count of a screw gauge.

When circular scale of a srew gauge carrying 100 divisions is given four complete rotations, the head of the screw moves through 2mm . The pitch and least count of screw gauge are respectively.

When circular scale of a screw gauge carrying 100 divisions is given four complete rotation, the head of the screw moves through 2mm. Calculate pitch and least count of the screw gauge.

What is the least count of a standard screw gauge

Least count of screw gauge is defined as.

Least count of screw gauge is defined as.

The head scale of a screw gauge has 200 division . Its head advances by 1 mm for 2 complete rotations of its head . Find its pitch and least count.

The meehanism behind nut and bolt arrangement also works for screw gauge. In case of nut and bolt mechanism, with rotation of bolt, it has translational movement also. In one complete rotation of bolt, tip of bolt moves by a linear distance equal to linear distance between two consecutive threads on the screw, known as pitch in case of screw gauge, the circular scale is divided in several parths. The ratio of pitch and total number of divisions on circular scale is known as least count. Spherometer is a device used to measure very small distances such as radius of curvature and thicness of thin plate. The screw gauge can be used to meaure diameter of a spherical sample. A screw gauge has 100 divisions on head scale and in 8 rotations distance covered is 8 mm. Least count of given screw gauge is
