- The distance between the centers of two holes can be checked with a vernier caliper. The position of the caliper in measuring the inside distance between two holes is shown in Figure 29-10. To determine the setting on the caliper, subtract the radius of each hole (one-half the diameter) from the center distance. In Exercises 19 through 23, give the hole diameters and the distances between centers. For each, determine (1) the main scale setting and (2) the vernier scale setting. All dimensions are in inches.arrow_forwardThe distance between the centers of two holes can be checked with a vernier caliper.
