UNITIZED STRUCTURAL BODY REPAIR EXAM FULLY UPDATED
EXAMINATION QUESTIONS AND CORRECT ANSWERS DESIGNED TO
ENSURE SUCCESSFUL RESULTS
Unibody: ANSWER components made of lightweight, stamped sheet metal that
are joined together to form a single unit.
Space Frame: Response Steel or plastic can be used to make body panels. Steel
can be classified as HSS, Intermediate, or Mild. Panels could conceal structural
or frame deterioration.
Crush Zones: A Response Rails and other structural elements are made to bend
and collapse at certain locations.
ANSWER for Collision Energy Management The safeguarding of passengers is
the aim. Structures in the front and back serve as crushable energy absorbers.
POI for Direct Damage. Locating and diagnosing it is simple.
The ANSWER propagation of collision energy outside the immediate impact
area is known as indirect damage. Split seam sealers, torn spot welds,
misaligned panels, steel buckles, broken glass, and chipped or cracked paint are
a few examples.
ANSWER for Passive Restraint Systems A service manual is required. No two
are alike.
Datum: ANSWER fictitious line or plane underneath the car. determines height.
Centerline: Response A vertical plane that runs from the car's front to back.
determines width. The vehicle's body structure can feature stamped marks. is
verified by looking at the vehicle's undamaged section's last three width
measurements.
Answer: No Planes plane that is vertical and moves side to side. Verified by
taking three length measurements from the vehicle's undamaged area.
ANSWER: Symmetry Equal on the car's two sides.
, Asymmetrical: Response uneven on the car's two sides. (Carefully spare the
tyre.)
Points of Reference: ANSWER Bolts or nuts, holes, points of mechanical
attachment, panel edges, door strikers, and opening corners. Common
tolerances range from =/.3mm (1/8) to 1mm (1.32).
Measurements with loads: ANSWER Drivetrain In
Measurements taken without load: ANSWER Drivetrain out
The ANSWER shortest distance between two reference sites is the point-to-
point measurement. Also known as "as the crow flies" . Steel or tram tape
measures are used.
Datum Dimensions: ANSWER height variations between reference sites, taken
at the Datum plane. laser measurement apparatus
ANSWER: Computerised Measuring System compare information kept in a
central database or software application. Obtain a hard copy of the
measurements. can observe while tugging.
Steel's response I am unable to determine what kind is visible. The service
handbook must be consulted.
The amount of force or pressure required to break or tear steel is known as its
tensile strength.
Yield Strength: ANSWER The amount of pressure or force required to
permanently deform steel.
PSI-ANSWER Tensile and yield strengths are given in pounds per inch. The
stronger the steel, the higher the number.
For space frames, ANSWER Cosmetic uses mild steel. Tears may be welded
without losing strength, and heat can help reduce stress. Strength of yield:
30,000 PSI
Answer for Intermediate Steel Small tears can be welded without losing
strength, and the structural and cosmetic yield strength of 30,000–70,000 PSI
may be impacted by excessive heat.
