A technician is using a standard dial caliper to measure the outside diameter of a steel sleeve. The main beam graduated in tenths of an inch shows a reading of 2.300 inches2.300\text{ inches}, and the dial indicator reads 0.045 inches0.045\text{ inches}. What is the total measured outside diameter of the sleeve in inches?

Cevap: 2.345 inches

Cevap

The total measured outside diameter of the steel sleeve is 2.345 inches2.345\text{ inches}.
To determine the total dimension on a dial caliper, the value from the main beam scale is added directly to the value shown on the dial indicator. Adding 2.300 inches2.300\text{ inches} from the beam to 0.045 inches0.045\text{ inches} from the dial indicator gives a total reading of 2.345 inches2.345\text{ inches}.

Adım Adım Çözüm

1
Read the measurement indicated on the main beam scale
Main beam reading is 2.300 inches2.300\text{ inches}
The main beam of a dial caliper provides the coarse measurement in inches and tenths of an inch.
2
Read the measurement indicated on the dial face
Dial indicator reading is 0.045 inches0.045\text{ inches}
The dial needle indicates thousandths of an inch to provide precision beyond the beam scale.
3
Add the beam scale reading to the dial indicator reading
2.300 inches+0.045 inches=2.345 inches2.300\text{ inches} + 0.045\text{ inches} = 2.345\text{ inches}
Total measurement on a dial caliper is the direct sum of the beam graduation and the dial pointer value.
