Answer to Question #210395 in Physics for Phumzile Zondi

Question

Describe why engineers or technicians may prefer a Vernier calliper to other measuring instruments

Answer 1

The primary benefit of the vernier caliper is that it has scales of measurement built into the tool. A fixed scale and a sliding scale are utilized to determine measurements to within .001 inches. Also, unlike most calipers, Vernier calipers can be used in a number of ways. One set of measurement jaws can be used to determine outer measurements while another set of jaws can be used for interior measurements. Additionally, a sliding bar at the rear of the tool can be used to determine depth measurements.

Variations to the Vernier caliper make its use even simpler. Dial calipers are a type of Vernier caliper in which a dial serves as the smaller scale (reading measurements within .099 inches). Even more accurate in reading are the digital Vernier calipers. These utilize a digital display to give a reading and can be quickly switched between standard and metric dimensions.
