Write the effect of changing the pitch from 1mm to 2mm on accuracy of measurement
Answers
Taking different physical measurements in the real life circumstances, is one of the most important parts of the physics studies and research works.
The accuracy is very necessary in the measurements taking,slight differences of 1 mm,can ruin the whole calculation.
That's why we have to be accurate as much as possible while we take any kind of vital measurements.
"Screw gauge which is also called micrometer is used to calculate or calibrate the accurate radius of curvature of the tiny objects which are mainly used in mechanical and electrical engineering machines.
The pitch scale is the circular scale present in the screw gauge is also known as least count scale. The least count and the accuracy are inversely proportional to each other. Due to parallax error human eye cannot take reading to certain accuracy.
Therefore the accuracy cannot be measured after certain limit."
