Deck 14: Straightening and Repairing Structural Damage

Question 1

The three most common methods used for ____________________ are hammering or shocking the metal, pulling the buckled and distorted metal to unlock the stressed areas and allow it to reflow, and by applying controlled amounts of heat.

Answer 1

stress relieving

Question 2

Technician A says that LIFO stands for "Least in is Farthest Out." Technician B says that the first damage caused by the collision is what should be repaired first. Who is correct?

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

Answer 2

D

Question 3

As a rule, the evidence of damage is greater near the indirect damage location, because the extent of damage is reduced as the energy is dissipated into the adjacent structure.

Answer 3

False

Question 4

The use of ____________________ involves sandwiching a layer of either soft wood or a plastic film between two thin layers of metal to reduce road noise and vehicle weight, while at the same time enhancing the strength of the metal considerably.

Question 5

PPE stands for personal protective equipment.

Question 6

Technician A says that a unibody vehicle is designed so that the energy thrust upon the vehicle during impact travels along the pre-determined load path. Technician B says that as a rule, as the damage travels deeper into the vehicle the path of damage and destruction becomes more wide-spread but less severe. until it stops. Who is correct?

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

Question 7

Technician A says the elastic factor in metal requires that it be pulled beyond its normal position when making repairs. Technician B says when using tension, the pulling device will seek its center to create a straight line of pulling force. Who is correct?

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

Question 8

The area where the pinch weld clamps are attached should be coated with anti-corrosion compound and painted to disguise marks left by the pinchweld clamps

Question 9

Technician A says that nearly any area is a potential pulling location so long as it is able to withstand the pulling forces exerted in the area. Technician B says that a very quick and easy way to pull on the outer panels is to install weld-on tabs, or sweat tabs, as they are often called, onto the surface and attach a pulling clamp to it. Who is correct?

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

Question 10

Technician A says heat to assist with stress relieving can be applied without consequence on a unibody vehicle. Technician B says turnbuckles are used to hold the door opening in place while pulls are being made to adjacent areas. Who is correct?

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

Question 11

The anchor points must be able to withstand the total of the cumulative forces applied when repairing the damage. No one part of the vehicle can withstand the total amount of the corrective forces that are applied.

Question 12

Technician A says that tension as a corrective force is more easily controlled than any other corrective force. Technician B says whenever pressure is used as a corrective force, the entire area between the pushing locations is affected equally. 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 use of tension distributes the corrective force throughout the area between the anchor point and the tie down locations. Technician B says whenever tension is used as a corrective force, the area at the attaching point is affected most. Who is correct?

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

Question 14

Technician A says that a BOF vehicle is anchored at the pinch welds. Technician B says that pull clamps may be used by attaching them directly to the damaged parts that will be replaced. Who is correct?

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

Question 15

When repairing collision damage, the technician must reverse the effect of the damaging forces.

Question 16

The most frequent frontal impacts are _______________ as the driver generally tries to steer away from the imminent impact

Question 17

Technician A says the tie down point for a for a unibody is the pinchweld area. Technician B says the tie down made on a BOF vehicle is accomplished with chains and other tensioners. Who is correct?

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

Question 18

Repairing the twist condition typically involves blocking the center section, using it as a ____________________, and moving the ends of the rail in the opposite directions of each other.

Question 19

Technician A says that a single hard pull is the best method for repairing unibody collision damage. Technician B says that the order of repair is less important than careful measurement . Who is correct?

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

Question 20

The two forms of force application methods or techniques commonly used for correcting collision damage are ____________________ and ____________________.

Question 21

When repairing collision damage, what is the sequence of repair?

Question 22

What is springback?

Question 23

What is diamond damage condition?

Question 24

Explain the theory of "Last in, First Out (LIFO)."

Question 25

Describe how hostile or external forces cause collision damage.
