1Most modern passenger cars use a unitized steel shell in which the floor, pillars, and rails form the primary load-carrying structure. What is this architecture called (모노코크)?

A.Body-on-frame (프레임 온 보디) ladder chassis with a bolted cab

B.Monocoque / unit-body (모노코크, 일체구조) in which stamped panels are welded into one stressed shell

C.Space-frame (스페이스 프레임) of welded extrusions with non-structural outer skins only

D.Cab-over (캡오버) layout, which is a cab position rather than a body architecture

Explanation: A monocoque or unit-body (모노코크, 일체구조) welds floor pans, rails, pillars, and roof into one stressed shell that carries bending, torsion, and crash loads. Passenger cars use this layout so crash energy can be managed through designed crush members while the passenger cell stays stiff.

2On a light truck with a separate chassis, which statement correctly describes body-on-frame (바디 온 프레임) construction?

A.The cargo body and cab are spot-welded to the frame rails so the body itself is the chassis

B.The engine mounts to the cab floor, and there is no longitudinal frame

C.A separate ladder or perimeter frame (프레임) carries powertrain, suspension, and crash loads, and the body is mounted to it

D.Only the bed is framed; the cab is always a full monocoque sharing no mounts with the chassis

Explanation: Body-on-frame (바디 온 프레임) uses a distinct ladder or perimeter frame as the backbone. The cab and box bolt or mount to that frame, so pulling and measuring often start from the frame rails and crossmembers rather than from a unitized passenger-cell shell.

3Which body pillar (필러) stands at the windshield and front-door hinge area and is a primary roof and frontal-offset load path?

A.B-pillar (B필러)

B.C-pillar (C필러)

C.D-pillar (D필러)

D.A-pillar (A필러)

Explanation: The A-pillar (A필러) runs beside the windshield from the cowl/hinge area into the roof rail. It takes frontal-offset and roof loads and locates the front door, so damage or sectioning here affects glass opening, door fit, and passenger-cell integrity.

4In a side collision, which member is designed as the main vertical load path between the rocker and the roof rail and often uses press-hardened steel?

A.Radiator support (라디에이터 서포트)

B.B-pillar (B필러 / 센터 필러)

C.Trunk torsion bar (토션 바)

D.Hood inner frame (후드 이너)

Explanation: The B-pillar (B필러, 센터 필러) ties the rocker (사이드실) to the roof rail and is the primary side-impact and rollover column. Many makers stamp it in press-hardened boron steel so the passenger cell resists intrusion while outer skins remain milder, more formable steel.

5What is the primary structural role of the rocker panel / side sill (사이드실, 로커패널) on a unit-body car?

A.It is only a cosmetic outer skin covering the floor pan flange

B.It is the lower longitudinal side member that ties A-, B-, and C-pillars and carries side-crash and bending loads

C.It is a detachable running board with no closed section

D.It replaces the rear frame rail on body-on-frame trucks

Explanation: The rocker or side sill (사이드실) is a closed-section lower rail along each side of the passenger cell. It joins the pillars, feeds side-impact loads into the floor, and works with the roof rail as a safety-cage beam, so sectioning or heating it without maker information can ruin crash performance.

6Why are front and rear crumple zones (크럼플 존, 충격흡수구간) engineered to crush in a crash rather than remain rigid?

A.To keep bumper covers from cracking in parking-lot taps only

B.To lengthen the crash pulse and absorb kinetic energy so occupant deceleration and passenger-cell intrusion stay controlled

C.To guarantee that high-strength cabin steels also fold at the same rate as the rails

D.To make the vehicle shorter after repair so wheelbase specifications no longer matter

Explanation: Crumple zones (크럼플 존) convert kinetic energy into plastic deformation of designed members (rails, crush cans, aprons). A longer, managed pulse lowers peak occupant deceleration while the passenger cell is intended to stay a rigid safety cage. Repair must restore that designed crush, not weld the zone solid.

7Which front-end part is primarily a styling and low-speed energy-management cover, as opposed to the structural bumper beam (범퍼 빔)?

A.Front side member / rail (프론트 사이드 멤버)

B.Subframe (서브프레임)

C.Strut tower (스트럿 타워)

D.Front bumper cover / fascia (범퍼 커버)

Explanation: The bumper cover (범퍼 커버) is a plastic fascia that presents the vehicle's shape and may house absorbers for low-speed contact. The metal or composite bumper beam behind it, plus the rails, carry real crash loads. Replacing only the cover does not restore structural beam or rail damage.

8In a unit-body front structure, what is the apron / inner fender (에이프런 패널) mainly doing during a frontal crash?

A.It only holds the fender liner clips and can be omitted after a collision

B.It ties the upper rail (shotgun) and strut tower into the cowl and helps manage frontal and offset loads

C.It is the spare-tire well in the trunk floor

D.It is the rear wheelhouse that absorbs rear-end mash

Explanation: The apron (에이프런) is the inner front-side panel that links the upper rail, strut tower, and cowl. In a frontal or offset hit it both crushes and feeds remaining load into the A-pillar and hinge pillar, so hidden apron buckle is a classic indirect-damage finding.

9Compared with mild steel outer panels, what is a practical shop consequence of high-strength steel (HSS, 고장력강) in rails and reinforcements?

A.HSS always melts at a lower temperature than mild steel, so MAG heat is never a concern

B.HSS has higher yield/tensile strength and less elongation, so it springs back more and is more easily weakened by uncontrolled heating

C.HSS can be torch-straightened at any temperature because the extra carbon prevents grain growth

D.HSS cannot be resistance-spot-welded, so every joint must be a long continuous bead

Explanation: HSS (고장력강) is stronger and less ductile than mild steel, so it resists hammer work, shows more springback, and can lose the strength the part was designed with if overheated. Shops treat heat, sectioning, and weld process as material-specific, not as generic mild-steel panel beating.

10Why have outer closures such as hoods, doors, and fenders historically used milder, more formable sheet than the passenger-cell cage?

A.Mild steel cannot be stamped, so those panels are always cast aluminum

B.Mild steel is reserved for B-pillars because it resists intrusion better than boron steel

C.Closures never see crash loads, so material choice is only about paint adhesion

D.Outer skins need stretch formability and dent-repairability, while the cage needs much higher strength

Explanation: Outer closures must stamp into complex styling surfaces and still allow conventional hammer-and-dolly or stud-pull repair. The safety cage uses HSS/AHSS/UHSS for intrusion resistance. Mixing those jobs in one grade would either crack in the press or fail in a crash.

Craftsman Motor Vehicles Body Repair: Suggested Study Strategy

1Master the datum plane, vehicle centerline, and zero reference planes used in 3D measurement systems and tram gauge diagonal triangulation.

2Understand the metallurgical differences and repair restrictions between mild steel, HSS, AHSS, and UHSS/boron steel (never heat or straighten UHSS above OEM temperature limits).

3Thoroughly review STRSW squeeze-type resistance spot welding parameters, GMAW MIG/MAG pulse settings, and CuSi3 silicon-bronze GMA brazing procedures.

4Memorize the diagnostic characteristics of structural misalignments: mash (length reduction), sag (vertical downward displacement), sway (lateral deflection), twist (rotational warp), and diamond (asymmetrical side rail shift).
