Vernier Caliper Questions 1) Why did you take more than one independent measurement for each dimension? - To be sure that we have a more precise measurement, knowing that might be possible errors. Some of these errors are systematic and personal errors. 2) What does the smallest division on the main scale of the vernier caliper correspond to? - The smallest division on the main scale of the vernier caliper corresponds to one millimeter. 3) Inspect the vernier scale and note that 10 vernier divisions correspond to 9 main scale divisions. Prove that the vernier can be used to make readings to 1/10nof a main scale division.

Unformatted text preview: The vernier scale has 10 divisions that correspond in length to 9 divisions on the main scale. Each vernier division is therefore shorter than a main-scale division by 1/10 of a main-scale division. the zero mark of the vernier scale coincides with the zero mark of the main scale. The first vernier division is 1/10 main-scale division short of a mark on the main scale, the second division in 2/10 short of the next mark on the main scale, and so on until the tenth vernier division is 10/10, or a whole division, short of a mark on the main scale. It therefore coincides with a mark on the main scale....
