Question

two techs are about to measure runout on a rotating surface. technician a says to use a micrometer and telescoping gauge. technician b says to use a vernier caliper. who is correct? select one: o a. technician a o b. technician b o c. both a and b o d. neither a nor b

Explanation:

Step1: Recall run - out measurement

To measure run - out on a rotating surface, a dial indicator is typically used.

Step2: Evaluate technicians' suggestions

A micrometer and telescoping gauge are used for measuring internal and external dimensions, not run - out. A Vernier caliper is used for linear measurements of length, depth, etc., not for run - out on a rotating surface. So neither technician is correct.

Answer:

d. Neither A nor B
