Chapter 33, Problem 1A

Read the metric vernier caliper measurement for this setting.

To determine

Find the metric Vernier caliper measurement for this given setting.

Answer to Problem 1A

Themetric Vernier caliper measurement is, $82.42\text{mm}$.

Explanation of Solution

Given:

The given setting is,

  

Calculation:

Given:

  

Read the main scale reading to the left of the zero graduation on the Vernier scale.

Eighty-one $1$ -millimeter division and two $0.5$ -millimeter division.

$81\times 1\text{mm}+2\times 0.5\text{mm}=82\text{mm}$

The $21\text{th}$ Vernier scale graduation coincides. Each Vernier scale graduation represents $\text{0}\text{.02}\text{mm}$.

The number of millimeters represented by $21$ divisions.

$\text{0}\text{.02}\text{mm}\times 21=0.42\text{mm}$

Vernier caliper reading $\text{=}82\text{mm}+0.42\text{mm}=82.42\text{mm}$

Hence the metric Vernier caliper measurement is, $82.42\text{mm}$.
