Question

what is the dial caliper measurement?
.190
1.080
0.897
1.690

Explanation:

Step1: Identify main - scale reading

The main - scale reading of the dial caliper is 1 inch (assuming standard imperial units as there are no metric markings visible and the caliper design is typical for imperial measurements).

Step2: Identify dial - scale reading

The dial scale has 100 divisions for 0.1 inches. Each division is 0.001 inches. The dial pointer is at 90. So the dial - scale reading is 0.090 inches.

Step3: Calculate total measurement

Add the main - scale and dial - scale readings. $1+0.090 = 1.090$ inches. However, it seems there is an error in the options provided as the closest correct - looking option considering the reading principles is 1.080 which might be due to a mis - reading or a wrong set of options. But if we assume some tolerance or mis - marking in the options, based on our reading method:

Answer:

1.080
