ASE Structural Analysis & Damage Repair 2

Question 1

When measuring a unibody vehicle for structural damage, which point on the body is used as the reference for all dimensional measurements?

Accepted Answer

The closest undamaged datum point

Answer

Datum points are established undamaged reference points used to verify correct dimensional measurements.

Question 2

A vehicle pulled in for repair shows a buckle in the rocker panel and a misaligned door. This indicates damage in which structural area?

Accepted Answer

The lower body / side structure

Answer

Rocker panel buckling and door misalignment indicate collapsed or shifted lower side structure.

Question 3

What term describes the condition where the centerline of the vehicle is bent into a banana-like shape?

Accepted Answer

Sidesway

Answer

Sidesway damage bends the structure sideways off the centerline.

Question 4

Which gauge is hung from reference points beneath a unibody to visually check for vertical and horizontal misalignment?

Accepted Answer

Centering (self-centering) gauges

Answer

Self-centering gauges hang under the body and reveal misalignment by their visual relationship.

Question 5

Before pulling on a damaged unibody, why must the vehicle be properly anchored?

Accepted Answer

To prevent the whole vehicle from moving instead of straightening

Answer

Anchoring holds the vehicle so pulling force straightens the structure rather than dragging the car.
