define least count describe the method to find the least count of screw gauge
Answers
Explanation:
Least count: The least count of the screw is defined as the distance moved by the tip of the screw when turned through one division of the head scale. Micrometer screw gauge is defined as an instrument that is used for measuring the diameter of thin wires, the thickness of small sheets such as glass or plastics.
Answer:
science of measurement, the least count of a measuring instrument is the smallest and accurate value in the measured quantity that can be resolved on the instrument's scale. ... A stopwatch used to time a race might resolve down to a hundredth of a second, its least count.
A screw gauge of 100 divisions will move the cap scale along the main scale by 1/100 of mm-0.01 mm. This is the minimum value up to which a screw gauge can measure and is known as its least count. Or it is defined as the ratio between the pitch of the screw and the number of divisions on the circular scale.
