Here are the answers to the mechanical test questions: 1. a) Absorb impacts and vibrations The suspension system's main function is to absorb shocks and vibrations from the road, providing a smooth ride and maintaining tire contact. 2. d) Transmit the engine power to the wheels The transmission system adjusts the engine's power and torque to the wheels, allowing for different speeds and driving conditions. 3. d) Provide electrical power to start the engine The battery provides the initial electrical power needed to crank the engine and start the vehicle. 4. a) To protect the occupants in case of collision The airbag system is a safety feature designed to deploy rapidly during a collision to cushion occupants and prevent serious injuries. 5. c) Control the direction of the vehicle The steering system allows the driver to control the direction of the vehicle by turning the wheels. 6. a) Thickness gauge A thickness gauge (or feeler gauge) is commonly used to measure and adjust the clearance between engine valves and their operating components. 7. b) Radiator The radiator is a key component of the cooling system that dissipates heat from the engine coolant, keeping the engine at an optimal operating temperature. 8. c) Engine oil Engine oil is essential for the lubrication system, reducing friction and wear between moving parts, and helping to cool the engine. 9. c) Tire pressure gauge A tire pressure gauge is specifically designed to measure the air pressure inside a vehicle's tires. 10. c) Brake fluid Brake fluid is a hydraulic fluid that transmits force from the brake pedal to the brake calipers or wheel cylinders, enabling the vehicle to stop. 11. a) Power steering pump The power steering pump generates hydraulic pressure that assists the driver in turning the steering wheel, reducing the effort required. 12. b) Multímetro (Multimeter) A multimeter is commonly used to diagnose electrical problems in a vehicle by measuring voltage, current, and resistance. 13. c) Carburador (Carburetor) In older vehicles, the carburetor is responsible for mixing air and fuel in appropriate proportions before it enters the engine's combustion chambers. 14. c) Reducir las emisiones y eliminar los gases de escape (Reduce emissions and eliminate exhaust gases) The exhaust system's function is to safely channel exhaust gases away from the engine, reduce noise, and convert harmful pollutants into less toxic substances. 15. a) Medir el contenido de oxígeno en los gases de escape (Measure the oxygen content in the exhaust gases) The oxygen sensor monitors the amount of oxygen in the exhaust gases, providing data to the engine control unit (ECU) to optimize the air-fuel mixture. 16. b) Detener el vehículo (Stop the vehicle) The primary function of the brake system is to slow down or stop the vehicle safely and efficiently. 17. b) Bujías (Spark plugs) Spark plugs are responsible for igniting the air-fuel mixture in the combustion chambers of an internal combustion engine. 18. a) Amortiguadores (Shock absorbers) Shock absorbers dampen the oscillations of the springs and help keep the wheels in constant contact with the road surface, improving stability and control. 19. d) Pistones (Pistons) Pistons are fundamental components of an internal combustion engine, converting the pressure from combustion into mechanical force to turn the crankshaft. 20.
