2.
What is another term for voltage?
Correct Answer
D. Pressure
Explanation
Voltage is often referred to as "electrical pressure" because it represents the force or pressure that pushes electric charges through a circuit. This analogy helps to understand the concept of voltage as the driving force behind the flow of electric current. Therefore, pressure is another term used to describe voltage.
3.
What does DOHC stand for?
Correct Answer
A. Double over head cam
Explanation
DOHC stands for "double over head cam". This refers to an engine design that has two camshafts located above the cylinder head. These camshafts control the opening and closing of the intake and exhaust valves. This configuration allows for better engine performance and efficiency compared to a single overhead cam (SOHC) design.
4.
A type of clutch?
Correct Answer
D. DiapHragm spring clutch
Explanation
A diaphragm spring clutch is a type of clutch that uses a diaphragm spring to engage and disengage the clutch mechanism. The diaphragm spring is a flat, circular spring that applies pressure to the clutch plate, allowing it to engage with the flywheel and transmit power from the engine to the transmission. This type of clutch is commonly used in vehicles as it provides a smooth and efficient operation, allowing for easy shifting of gears.
5.
Name the gearbox component?
Correct Answer
B. Input shaft
Explanation
The correct answer is "input shaft". The input shaft is a component of a gearbox that transfers torque from the engine to the transmission. It connects to the clutch and receives power from the engine, allowing it to rotate and transmit power to the gears within the gearbox. This component is essential for the proper functioning of the gearbox and the overall operation of the vehicle.
6.
Give the approx bhp of the buggatti veyron?
Correct Answer
C. 1000
Explanation
The approximate brake horsepower (bhp) of the Bugatti Veyron is 1000. Brake horsepower is a unit of measurement used to determine the power output of an engine. In the case of the Bugatti Veyron, its engine produces approximately 1000 bhp, making it an incredibly powerful and high-performance vehicle.
7.
Name the three braking components.
Correct Answer
B. Caliper,disc,shoe
Explanation
The correct answer is caliper, disc, shoe. The caliper is responsible for applying pressure to the disc, which in turn slows down the rotation of the wheel. The shoe is a curved piece of material that presses against the inside of the drum to create friction and slow down the vehicle. These three components work together to effectively stop the vehicle when the brakes are applied.
8.
Which one is the real formula 1 driver?
Correct Answer
D. Mark webber
Explanation
Mark Webber is the correct answer because he is a former Formula 1 driver. Jenson Button is also a former Formula 1 driver, but the question asks for the "real" Formula 1 driver, implying that only one of the options is a genuine Formula 1 driver. Juan Veron and Tiff Needell are not Formula 1 drivers, so they are not the correct answer.
9.
What country does Renault originate from?
Correct Answer
A. France
Explanation
Renault originates from France. Renault is a French multinational automobile manufacturer that was founded in 1899. The company has its headquarters in Boulogne-Billancourt, France. Renault is known for producing a wide range of vehicles, including cars, vans, trucks, and even motorcycles. The brand has a long history in the automotive industry and has become one of the leading car manufacturers in France and globally.
10.
What color fire extinguisher contains water?
Correct Answer
D. Red
Explanation
Red fire extinguishers typically contain water and are used for extinguishing fires caused by ordinary combustible materials such as wood, paper, and textiles. The red color is used to easily identify these specific fire extinguishers and differentiate them from other types that contain different extinguishing agents.
11.
Which component links the gearbox to the final drive on a rear-wheel-drive vehicle?
Correct Answer
D. Prop shaft
Explanation
The prop shaft, also known as the propeller shaft or drive shaft, is the component that connects the gearbox to the final drive on a rear-wheel-drive vehicle. It transmits the rotational power from the gearbox to the differential, which then distributes the power to the rear wheels. The prop shaft is a crucial part of the drivetrain system, allowing the engine's power to be transferred to the wheels efficiently and smoothly.
12.
Which component opens and closes to release exhaust gasses from the cylinder?
Correct Answer
C. Valve
Explanation
The valve is the component that opens and closes to release exhaust gases from the cylinder. It acts as a gate, allowing the gases to exit the cylinder during the exhaust stroke of the engine. The valve is operated by the camshaft, which controls its timing and duration of opening and closing. This process is essential for the proper functioning of the engine, as it allows for the removal of spent gases and the intake of fresh air-fuel mixture for combustion.
13.
What is the top speed of the Bugatti Veyron?
Correct Answer
A. 253mpH
Explanation
The Bugatti Veyron has a top speed of 253mph.
14.
Name 2 types of suspension spring?
Correct Answer
C. Leaf spring , coil spring
Explanation
The correct answer is leaf spring, coil spring. Leaf springs are made up of multiple layers of curved metal strips, providing flexibility and support for heavy loads. Coil springs, on the other hand, are helical-shaped springs that compress and expand to absorb shocks and maintain stability. Both types of springs are commonly used in suspension systems to provide a smooth ride and improve the handling of vehicles.
15.
What is the minimum tread depth allowed in the UK?
Correct Answer
A. 1.6mm
Explanation
The minimum tread depth allowed in the UK is 1.6mm. This measurement refers to the depth of the grooves on a tire's surface. Adequate tread depth is essential for maintaining traction and grip on the road, especially in wet or slippery conditions. Tires with tread depth below the legal limit can compromise safety and increase the risk of accidents. Regularly checking and maintaining proper tread depth is important for ensuring the overall performance and safety of vehicle tires.
16.
What gets into brake fluid and causes the pedal to be spongy?
Correct Answer
A. Air
Explanation
Air can get into brake fluid and cause the pedal to be spongy. When air enters the brake system, it creates air bubbles in the brake fluid. These air bubbles can compress, causing the brake pedal to feel soft or spongy when pressed. This can lead to a decrease in braking performance and potentially compromise the safety of the vehicle. It is important to regularly check and maintain the brake fluid to prevent air from entering the system.
17.
Which component attaches the piston to the crankshaft?
Correct Answer
D. Con rod
Explanation
The con rod, also known as the connecting rod, is the component that attaches the piston to the crankshaft in an engine. It connects the piston to the crankshaft journal, allowing the reciprocating motion of the piston to be converted into rotary motion by the crankshaft. The con rod plays a critical role in transferring the force generated by the combustion process to the crankshaft, enabling the engine to produce power.
18.
What is the main purpose of a radiator in a car?
Correct Answer
D. Cool down engine
Explanation
The main purpose of a radiator in a car is to cool down the engine. As the engine runs, it generates a lot of heat, and the radiator helps to dissipate this heat by circulating coolant through the engine. The coolant absorbs the heat from the engine and then flows through the radiator, where it is cooled down by the airflow passing through the radiator fins. This process helps to prevent the engine from overheating and ensures that it operates at an optimal temperature.
