Safety
What is the primary purpose of wearing safety goggles in an automotive shop?
To protect the eyes from debris and harmful chemicals.
What is the basic function of an internal combustion engine?
To convert fuel into mechanical energy.
What is the purpose of a car battery?
To store electrical energy to start the vehicle and power electrical components.
What are the two main types of brake systems found in vehicles?
Disc brakes and drum brakes
What is the primary function of a vehicle's suspension system?
To support vehicle weight, absorb shocks, and maintain tire contact with the road.
Name one common hazard found in an automotive service environment.
Oil spills, electrical hazards, heavy lifting, etc.
Name the four strokes of a four-stroke engine cycle.
Intake, compression, power, exhaust
Name one component of the vehicle's electrical system.
Alternator, starter, wiring harness, etc.
Squeaking noise, reduced responsivness, or warning lights.
Name one type of steering system used in automobiles.
Rack and pinion, recirculating ball, etc.
What is the correct method for lifting a vehicle safely?
Use jack stands and follow proper lifting procedures.
What role does the oil play in an engine?
Lubricates moving parts, reduces friction, and helps cool the engine.
How does a starter motor work?
It engages the engine flywheel to start the engine.
What is the purpose of brake fluid?
To provide hydraulic pressure for braking.
How does a shock absorber work?
It dampens the impact of road bumps to provide a smooth ride.
Describe the importance of Material Safety Data Sheets (MSDS) in the shop.
MSDS provide information on the hazards of materials used in the shop and how to handle them safely.
Identify one type of engine cooling system.
Radiator or liquid cooling system
What is the function of a fuse in a vehicle?
Explain the difference between disc brakes and drum brakes.
Disc brakes use a rotor and a caliper; drum brakes use a drum and brake shoes.
Uneven tire wear, vehicle pulling to one side, or bouncing ride.
What are the steps to take in case of an accident in the shop?
Administer first aid, report to supervisor, and document the incident.
Explain the difference between a two-stroke and a four-stroke engine.
Two-stroke engines complete a power cycle in two strokes of the piston; four-stroke engines complete it in four strokes.
Describe the process of how a car's alternator charges the battery.
The alternator generates electricity while the engine runs, converting mechanical energy to electrical energy to recharge the battery.
What are anti-lock braking systems (ABS) and how do they work?
ABS prevents wheel lock-up during braking, allowing for steering contol.
Proper alignment ensures even tire wear and improves handling and control.
