Question 1

11)Technician A says that the micrometer operates on a simple principle: The spindle has 20 threads per inch, so one revolution of the thimble will advance or retract the spindle 1/20 of an inch. Technician B says that spindle has 50 threads per inch, so one revolution of the thimble will advance or retract the spindle 1/50 of an inch. Who is correct?

A) A only
B) B only
C) Both A and B
D) Neither A nor B

Answer 1

D

Question 2

13)Which of the following is LEAST-Likely a type of dial indicator face?

C

Question 3

3)The temperature at which water freezes is zero degrees Celsius (0°C). Water boils at 100°C.

Answer 3

True

Question 4

17)The metric unit of weight is the ____________________, which is the weight of the amount of water it takes to fill a cube that is 1/100 of a meter long on each side.

Question 5

20)An inside micrometer cannot work in cylinders smaller than about 2", so telescoping or small-hole gauges are used. These are known as ____________________ gauges.

Question 6

8)While discussing measuring tools, Technician A says that when measuring clearance with a feeler gauge, there should be a slight drag when the feeler strip is moved through the area of clearance. Technician B says that if a feeler gauge that is 0.001" thicker will not fit into the gap, the correct measurement has been made. Who is correct?

A) A only
B) B only
C) Both A and B
D) Neither A nor B

B) a dial indicator can measure movements such as end play of crankshafts and valve guide wear.
C) inside micrometers have extension rods to make them the proper size.
D) the thimble of an inside micrometer does not move as freely on the barrel as the thimble of an outside micrometer.

Question 12

5)An inside micrometer can be used to measure cylinder bores and main and rod bearing bores.
