Sample Karnataka II PUC Automobile — Vocational (KSEAB) Practice Questions

Try these sample questions to review concepts for the Karnataka II PUC Automobile — Vocational (KSEAB) exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1In II PUC automobile theory, a complete chassis is best described as the:
A.Structural framework that supports the body, power unit, and major systems
B.Passenger cabin air-conditioning module only
C.Infotainment display assembly
D.Spare-wheel cover and mud flaps only
Explanation: The chassis is the vehicle’s structural backbone. It supports the body, engine/transmission, suspension mounts, and other major units and carries operating loads. HVAC, screens, and wheel covers are not the chassis.
2Ladder-type frames used on many commercial vehicles are primarily constructed from:
A.Steel channel or box sections forming side members and cross-members
B.Only tempered glass sheets bolted edge-to-edge
C.Inflatable rubber beams
D.Cardboard honeycomb panels
Explanation: Ladder frames use steel side rails (often channel or box section) joined by cross-members for strength under load. Glass, rubber-only beams, and cardboard are not structural frame materials for commercial chassis.
3Unibody (monocoque) construction differs from a separate body-on-frame design mainly because:
A.Body panels and structure form an integrated shell that carries loads
B.The body never bolts to any structural member
C.Only the radiator supports the vehicle weight
D.There is never a floor pan or pillars
Explanation: In unibody construction, the body shell (floor, pillars, rails) is designed as an integrated structure that carries crash and operating loads. Body-on-frame uses a separate ladder/chassis frame. Unibodies still have floor pans and pillars; the radiator does not support vehicle weight.
4The main purpose of cross-members in a ladder chassis is to:
A.Tie the side rails together, increase torsional rigidity, and support mounted units
B.Store spare fuel exclusively
C.Generate spark for ignition
D.Measure tyre tread depth
Explanation: Cross-members connect left and right side rails, resist twisting, and provide mounting points for the engine, transmission, and other units. They are structural, not fuel tanks, ignition sources, or tread gauges.
5A stub axle is primarily associated with:
A.Supporting a steered front wheel and connecting it to the steering knuckle/axle end
B.Mixing air and diesel in the combustion chamber
C.Charging the battery through the alternator only
D.Cooling the cabin evaporator
Explanation: Stub axles (or steered axle ends) carry the front wheels and form part of the steered knuckle assembly. Mixture formation, charging, and A/C cooling are other systems.
6Which statement correctly describes a live rear axle in a conventional RWD vehicle?
A.It transmits drive torque to the rear wheels while also supporting vehicle weight
B.It never carries torque and is used only for decoration
C.It only steers the front wheels
D.It stores engine oil for the sump
Explanation: A live rear axle both supports load and delivers driving torque through the final drive to the wheels. Dead axles support load without driving. Live rear axles do not steer the front wheels or store engine oil.
7Vehicle classification by propulsion commonly groups automobiles into:
A.ICE (petrol/diesel), hybrid, battery-electric, and other powertrain types
B.Only red-coloured and blue-coloured vehicles
C.Only vehicles with cloth seats
D.Only vehicles registered before 1990
Explanation: Standard classification by power unit groups vehicles as internal-combustion, hybrid, pure electric, and related variants. Colour, seat fabric, and registration year are not propulsion classes.
8Wheelbase is defined as the:
A.Distance between the centre of the front wheel and the centre of the rear wheel on the same side
B.Width between the outer edges of the two front tyres only
C.Height from ground to roof antenna only
D.Volume of the fuel tank in litres
Explanation: Wheelbase is the longitudinal distance between front and rear wheel centres (same side). Track is lateral width between wheels; roof height and fuel volume are different dimensions.
9If a car’s wheelbase is 2.70 m and the rear overhang is 0.90 m, the distance from the rear wheel centre to the rear bumper line (overhang) is:
A.0.90 m as given; wheelbase alone does not change that overhang figure
B.2.70 m because overhang equals wheelbase
C.3.60 m (sum of wheelbase and overhang must always be the overhang)
D.0.30 m (wheelbase divided by nine always)
Explanation: Rear overhang is an independent body dimension: the horizontal distance from the rear wheel centre line to the rear extremity. The problem already states rear overhang as 0.90 m; wheelbase is a separate dimension used for other layout calculations.
10A frame that uses a central longitudinal backbone with outriggers for body mounts is called a:
A.Backbone frame
B.Only a pure ladder frame with two continuous side channels and no backbone
C.Space-frame made exclusively of glass
D.Tyre carcass frame
Explanation: A backbone frame uses a strong central tube/spine with outriggers for body and suspension mounts (seen on some cars and specialized vehicles). Ladder frames use dual side rails; glass space-frames and tyre carcasses are not this design.

About the Karnataka II PUC Automobile — Vocational (KSEAB) Exam

Karnataka II PUC Automobile is the Class 12 vocational Automobile subject under the Karnataka School Examination and Assessment Board (KSEAB), subject code 63 on the II PUC blueprint and model-question-paper hubs (dpue-exam). It develops service-technician theory beyond SSLC NSQF Automobile: chassis and load paths, engine systems (including compression ratio and power terms), workshop metrology and tools, safety, service manuals and component serviceability, auto electrical circuits and calculations, tyres and brakes, suspension/steering/driveline (clutch, prop shaft, differential, gear ratios), and employability skills. Official assessment combines mixed written theory (model materials commonly cite about 60 marks, about 37 questions, about 2 h 15 min) with practical/skill and internal components. Fees and exact blueprints are notified on kseab.karnataka.gov.in and dpue-exam portals; pass marks are commonly described around 35% overall with component rules. The 100 questions on this page are a free English-language multiple-choice theory study adaptation; they are not a substitute for practical workshop assessment or a full simulation of the official mixed paper.

Karnataka II PUC Automobile — Vocational (KSEAB): Suggested Study Strategy

1Download official code 63 model papers (typically three MQPs) and the Automobile blueprint from dpue-exam so you can switch from MCQ drills to VSA/SA/ET writing.
2Treat workshop practicals as mandatory: theory MCQs cannot replace measurements, clutch/service procedures, or safety demonstrations.
3Memorize service-manual uses (torque, diagrams, procedures) and job-card documentation — these are blueprint unit themes.
4Drill auto-electrical hard: Ohm’s law, series/parallel, battery precautions, fuse protection, and warning-lamp logic (high official weight).
5Practise compression-ratio, IHP/BHP/FHP, and simple gear-ratio calculations with units shown.
6Learn clutch location, diaphragm clutch traits, prop shaft path, and differential function for transmission unit questions.
7Review employability: product knowledge, clear estimates/approval, and ethical handling of customer data.
8Use English-medium model papers if you study in English; Kannada-medium candidates should also practise official board wording from KSEAB/DPUE sources.
