Vernier Caliper Essay

THE VERNIER AND THE MICROMETER CALIPERS

I. Data

Table you: The Vernier Caliper

Least count= 1/20 mm

Object| Composition| Dimensions| Amount (cm3)| Mass| Density| Cube| Copper| Side length= 18. 22 mm| 60. three or more cm3| 70. 4 g| 10. 02 g/cm3| Sphere| Iron| Diameter= 11 mm| 0. 75 cm3| several. 3 g| 10. some g/cm3| Cylinder| Lead| Diameter= 18. you mm

Height= 25. being unfaithful mm| 6th. 66 cm3| 52. some g| six. 87 g/cm3

Washer| Iron| Outer diameter= 35. 15 mm

Inner diameter= 15. 7 millimeter

Thickness= installment payments on your 8 mm| 8. 7 cm3| sixteen. 5 g| 1 . on the lookout for g/cm3

Table 2: The Micrometer Caliper

Least count= 1/100 mm

Object| Composition| Dimensions| Volume (cm3)| Mass| Density| Cube| Copper| Side length= 19. one particular mm| six. 87 cm3| 60. 4 g| 8. 79 g/cm3| Sphere| Iron| Diameter= 12 mm| zero. 91 cm3| 7. 3 g| almost 8. 02 g/cm3| Cylinder| Lead| Diameter= nineteen. 11 mm

Height= N/A| N/A| 52. 4 g| N/A

Washer| Iron| External diameter= N/A

Inner diameter= N/A

Thickness= 3. two mm| N/A| 16. five g| N/A

II. Contrasting the denseness of the subject obtained from the experiment with some of the density, which is more accurate, the Vernier Caliper reading or the Micrometer Caliper reading? Fix for the proportion error. Nonius Caliper:

Object| Density| Percentage Error

| Theoretical Value| Experimental Value|

Cube| 8. 96 g/cm3| 12. 02 g/cm3| 11. 83%

Sphere| 7. 87 g/cm3| 10. four g/cm3| thirty-two. 15%

Cylinder| 11. thirty six g/cm3| several. 87 g/cm3| 30. 72%

Washer| several. 87 g/cm3| 1 . 9 g/cm3| seventy five. 86%

Micrometer Caliper:

Object| Density| Percentage Error

| Theoretical Value| Experimental Value|

Cube| 8. 96 g/cm3| eight. 79 g/cm3| -1. 90%

Sphere| 7. 87 g/cm3| 8. 02 g/cm3| 1 ) 91%

Cylinder| 11. thirty six g/cm3| N/A| N/A

Washer| 7. 87 g/cm3| N/A| N/A

From this experiment, the Micrometer caliper is more exact than the Vernier caliper. Formula used:

III. How would you realize that the instrument is more correct than the various other by just taking a look at their least count? The accuracy of the...
