Chapter 32, Problem 1A

Read the decimal-inch vernier caliper measurement for this setting.

To determine

The measurement in the given Vernier scale.

Answer to Problem 1A

  $2.605$ Inch.

Explanation of Solution

Given information:

Calculation:

To obtain the main scale reading: Look at the image, $2.6$ inch is to the immediate left of the zero on the Vernier scale. Hence, the main scale reading is $2.6$ inch.

To obtain the Vernier scale reading: Look closely at the image for an alignment of the scale lines of the main scale and Vernier scale. In the image, the aligned line corresponds to 5. Hence, the Vernier scale reading is $0.001$ cm.

In order to obtain the final measurement reading, add the main scale reading and Vernier scale reading together. This will give $2.6$ inch $+0.005$ inch $=2.605$ inch.

Hence, final measurement reading, from given image is found $2.605$ inch.
