Technician A says that a micrometer can be used to measure the outside diameter of something. Technician B says that a vernier caliper can be used to measure the inside diameter of a bore. Who is correct? a . Tec A b. Tec B. c.Both A and B. d. Neither A nor B.
Solution:
Explanation: We know that micrometer is used to measure the outside diameter of objects (say shaft, rod etc.)
Vernier caliper can be used to measure the inside diameter of a bore (say hole, groove etc.). Vernier caliper can also be used to measure the outside diameter of objects.
Thus, Option C (Both A and B) is correct. (Answer)
Technician A says that a micrometer can be used to measure the outside diameter of something....
