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.

Accepted Answer

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?

Accepted Answer

Technician A is incorrect. LIFO stands for "Last in First Out," not "Least in is Farthest Out." Technician B's statement is also incorrect because the approach to repairing collision damage should be based on a proper assessment of the extent of the damage, not which damage was caused before the other. Therefore, neither technician is correct.

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.

Accepted Answer

The statement is incorrect because typically, the evidence of damage is greater near the direct damage location, where the energy impact is highest, and tends to decrease as you move away from the point of impact, where the energy has been dissipated.

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.

Accepted Answer

The answer of The use of ____________________ involves sandwiching a...

Question 5

PPE stands for personal protective equipment.

Accepted Answer

PPE stands for personal protective equipment, which includes clothing and other equipment designed to protect individuals from workplace hazards.

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?

Accepted Answer

Both technicians are correct. Unibody construction is designed to distribute collision forces along predetermined load paths to protect occupants. As the damage travels deeper into the vehicle, the path of destruction does become more widespread, but typically less severe until it is stopped by the vehicle's frame or structural components.

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?

Accepted Answer

Both technicians are correct. Technician A refers to the need to stretch metal slightly beyond its original shape to account for the elastic properties of metal, ensuring it returns to its correct form after repair. Technician B is correct in stating that when applying tension in repairs, the pulling force will naturally seek the shortest, most direct path, aligning with the center of the force application, which helps in achieving a straight and proper repair.

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

Accepted Answer

The answer of The area where the pinch weld 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?

Accepted Answer

Both technicians are correct. Nearly any area can be used as a potential pulling location as long as it can withstand the pulling forces. One quick and easy way to pull on outer panels is to install weld-on tabs or sweat tabs onto the surface and attach a pulling clamp to them.

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?

Accepted Answer

Technician B is correct because turnbuckles are indeed used to hold door openings or other structural elements in place while repairs are being made to adjacent areas, ensuring the structure does not deform during the repair process. Technician A is incorrect because applying heat to assist with stress relieving on a unibody vehicle must be done with caution due to the potential for damaging the vehicle's structural integrity or altering its metallurgical properties.

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.

Accepted Answer

This statement is true. The anchor points must be distributed throughout the vehicle and able to withstand the total of the cumulative forces applied during repairs. No single part of the vehicle can withstand the total amount of corrective forces that are necessary to properly repair the damage.

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?

Accepted Answer

Tension as a corrective force is more easily controlled because it can be adjusted by adjusting the amount of pulling force. Pressure, on the other hand, affects the entire area between the pushing locations equally, which can lead to unintended consequences. Therefore, Technician A is correct and Technician B is incorrect.

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?

Accepted Answer

Technician A is correct. The use of tension distributes the corrective force throughout the area between the anchor point and the tie down locations. Technician B is incorrect as the area at the attaching point is not affected most.

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?

Accepted Answer

The answer of Technician A says that a BOF vehicle...

Question 15

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

Accepted Answer

To repair collision damage, the technician must reverse the effect of the damaging forces by restoring the vehicle's structural integrity and appearance to its pre-accident condition.

Question 16

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

Accepted Answer

The answer of The most frequent frontal impacts are _______________...

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?

Accepted Answer

Technician A is correct because the pinchweld area is a common tie down point for unibody vehicles, providing a strong location for securing the vehicle without causing damage. Technician B is also correct because body-on-frame (BOF) vehicles are often tied down using chains and tensioners due to their robust frame construction, allowing for secure attachment points that can handle the tension without damage.

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.

Accepted Answer

The answer of Repairing the twist condition typically involves blocking...

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?

Accepted Answer

Neither technician is correct. The best method for repairing unibody collision damage depends on the specific type and severity of the damage. Additionally, careful measurement is important but it is not more important than following the correct repair procedures.
