Deck 13: Measuring Structural Damage

Question 1

Technician A says that "twist" is a condition in which a section of the undercarriage is moved or shoved to one side or the other. Technician B says that "sidesway" is a type of damage that typically occurs in the center section of the vehicle, frequently radiating out to either the front or rear of the vehicle. Who is correct?

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

Answer 1

D

Question 2

There are a number of measuring systems that are dependent upon the computer to store, retrieve, and simultaneously compare dimensional information for the vehicle being repaired.

Answer 2

True

Question 3

Technician A says the center plane is used to take height measurements. Technician B says the measuring the control points are all used for base or zero locations for 3 dimensional measuring systems. Who is correct?

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

Answer 3

D

Question 4

Technician A says that when making point to point measurements with a tram gauge, the pin location should be equal distances from the bar on both ends. Technician B says when making comparative side to side measurements the reference points on the undercarriage specifications must always be used.. Who is correct?

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

Question 5

Technician A says the centering gauges can be used to determine the datum plane. Technician B says the height measurements are taken from the center line. Who is correct?

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

Question 6

Technician A says that diamond condition is one in which one of the side rails has been struck hard at the front causing it to be moved back, often over the entire length of the vehicle Technician B says that a tape measure should not be used to measure structural tolerances. Who is correct?

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

Question 7

The point zero plane is the area from which most of the undercarriage measuring systems take their measurements

Question 8

Technician A says that "mash" is a condition in which one or both of the rails are shorter than the manufacturer's specifications. Technician B says that "sag" is a condition in which one or both of the rails are shorter than the manufacturer's specifications. Who is correct?

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

Question 9

The Car-O-Tronic measuring system requires only ____________________ undamaged points to establish a foundation for measuring. One must keep in mind that this only establishes length and width dimensions until a third point can be established.

Question 10

A tool that is frequently used for height measuring is a tram gauge, or tram bar.

Question 11

A laser device is an optical device which uses a quantum stimulated emission discovered by Albert Einstein.

Question 12

Technician A says that point to point measurements can be used to check the squareness of virtually any opening or area of the vehicle. Technician B says that the tool that is frequently used for point to point measuring is a tracking gauge. Who is correct?

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

Question 13

Technician A says the centering gauge frequently requires removing several suspension parts prior to securing it to the bench. Technician B says the electro-mechanical measuring system can monitor only one location at a time. Who is correct?

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

Question 14

Occasionally when a technician is diagnosing damage, it becomes necessary to make some quick ____________________ diagonal measurements to determine the exact location of a misaligned section of a vehicle.

Question 15

As the name implies, ____________________ measurements are derived by measuring the distances between two points on the vehicle.

Question 16

Technician A says that a collision-damaged vehicle must be restored to within 5 MM of the manufacturer's original specifications. Technician B says that "sag" is a condition in which one of the side rails has been struck hard at the front causing it to be moved back, sometimes over the entire length of the vehicle. Who is correct?

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

Question 17

The four corners under the passenger compartment, or more precisely, the torque box areas, are the primary control points from which the majority of the measurements originate. For this reason, this area is also referred to as the ____________________ area.

Question 18

A tool that is frequently used for point to point measuring is a ____________________ . .

Question 19

The center plane is used to take side to height measurements.

Question 20

Technician A says the digital measuring system is a "go or no go" system. Technician B says that when making point to point measurements where a large hole is used as a reference point, it may be advisable for the technician to measure edge to edge for more accuracy. Who is correct?

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

Question 21

Discuss the difference between primary and secondary damage.

Question 22

What is a quick check measurement?

Question 23

Explain primary damage.

Question 24

Describe mash.

Question 25

What is a datum plane?
