Question

Define vernier Calliper...???​

Answer 1

Answer:

A vernier scale is a visual aid to take an accurate measurement reading between two graduation markings on a linear scale by using mechanical interpolation; thereby increasing resolution and reducing measurement uncertainty by using vernier acuity to reduce human estimation error.

Answer 2

__________________________________

Answer,

• A vernier scale is a visual aid to take an accurate measurement reading between two graduation markings on a linear scale by using mechanical interpolation; thereby increasing resolution and reducing measurement uncertainty by using vernier acuity to reduce human estimation error.

• Purpose: Measuring more precisely than could be done unaided when reading a uniformly divided straight or circular measurement scale

• Creator: Pierre Vernier

Year invented: 1631

• Uncertainty :The Vernier caliper is an instrument that allows you measure lengths much more accurate than the metric ruler. The smallest increment in the vernier caliper you will be usingis ( $\bf\dfrac{1}{50}$ )mm = 0.02mm = 0.002cm. Thus, the uncertainty is ∆x = ( $\bf\dfrac{1}{2}$ )0.002 cm = 0.001 cm.
