Question

caliper measurement: what is the measurement of this part in millimeters? * 1 point 22.68 mm 2.7 cm 22.068 mm 21.68 mm

Explanation:

Step1: Read the main scale

The main scale reads 22 mm.

Step2: Read the dial scale

Each small division on the dial is 0.02 mm. The dial hand is at 68, so \(68\times0.02 = 1.36\) mm.

Step3: Calculate total measurement

Add main - scale and dial - scale measurements: \(22+1.36=23.36\) mm. Wait, no, re - check. Wait, maybe mis - read. Wait, if we assume the main scale is 22 mm (each big division is 10 mm, and it's past 20 mm mark, 22 mm). The dial: if each big division on dial is 0.1 mm (since 10 divisions for 0.1 mm, each small division 0.01 mm). Wait, no, standard dial caliper: main scale in mm (each big division 10 mm, each small division 1 mm). Dial: 100 divisions for 1 mm (so each division 0.01 mm). If the dial hand is at 68, then \(0.68\) mm. Total \(22 + 0.68=22.68\) mm.

Answer:

22.68 mm
