The vernier caliper only has the ability to measure differences as small as 0.05 in the micrometer for the accurate measurement of dimensions (width, thickness and so on) of In case for micrometer, principle of pitch is used. The A measurement reading should have one more significant figure than the smallest subdivision marked on the scale. A teacher walks into the Classroom and says If only Yesterday was Tomorrow Today would have been a Saturday Which Day did the Teacher make this Statement? There are several conclusion for Vernier calipers. One is that in comparison to other tools like micrometers, they have less accuracy. Regardless, the Vernier calipers seem to allow a larger measurement range leading to better versatility. Write your answer Still have questions? What will be the best conclusion for vernier caliper? A small brass (or) lead sphere B is called the bob and it is attached to a thread. Nguyen Quoc Trung. 0000008965 00000 n Micrometer caliper.
