The answer also includes the class B-C, which indicates that this class of fire extinguisher is also necessary. Therefore, the correct answer is 2,A-B-C.

The correct answer is 12*2*0.1968 inches. This is because the question is asking for the dimensions of the jack point, and the only option that provides specific dimensions is 12*2*0.1968 inches. The other options either have different measurements or do not provide any specific dimensions at all.

According to the rulebook, a driver must have a total vision range of 200°. This means that the driver should be able to see objects and surroundings within a 200° field of view. This is important for ensuring the safety of the driver and others on the road, as it allows for better awareness of the surroundings and potential hazards.

Teams in the Adventure class are not allowed to place panels on the roof or over the head of the driver. This implies that the correct answer is False.

The correct answer is 3 because kill switches are safety devices that can shut off the engine or electrical power in case of an emergency or to prevent theft. Having multiple kill switches increases the overall safety of the vehicle as it provides redundancy in case one switch fails or malfunctions. Therefore, it is recommended to have at least three kill switches in a vehicle to ensure maximum safety.

The correct answer is 90 mm, 165.1 mm. This means that the minimum tread width of the tire should be 90 mm and the maximum tread width should be 165.1 mm. The tread width is the measurement of the width of the tire's contact surface with the road. Having a minimum and maximum tread width ensures that the tire has enough contact with the road for proper traction and stability while also allowing for variations in tire design and performance.

The correct answer is 0.10%. When steel is used in the frame, it is important to have a minimum carbon percentage of 0.10%. This is because carbon enhances the strength and hardness of steel, making it suitable for structural applications like frames. However, having too high of a carbon percentage can make the steel brittle, so a minimum value of 0.10% strikes a balance between strength and ductility.

The distance from the hip point to the top of the head restraint must be 800 mm. This measurement is important for ensuring proper safety and comfort for the occupant. It is crucial to maintain the correct distance to prevent injury during sudden stops or accidents. A distance of 800 mm strikes the right balance between providing adequate support to the head and neck while also allowing for comfortable seating position.

The suspension used must have a total travel of 4 inches as mentioned in the rulebook. This means that the suspension system of the vehicle should be able to compress and extend up to a maximum of 4 inches. This requirement is likely mentioned in the rulebook to ensure that all vehicles participating in the competition have a similar level of suspension performance, which can affect the overall handling and safety of the vehicle.

The brake over travel switch must be wired in series as mentioned in the rulebook. This means that the switch should be connected in a circuit where the current flows through the switch before continuing to the rest of the components. Wiring it in series ensures that the switch will interrupt the circuit and prevent the brake from overtraveling when it is activated.

A tadpole shape is allowed in a three-wheel vehicle. A tadpole shape refers to a configuration where the two wheels are located in the front and a single wheel is located at the rear. This configuration provides better stability and maneuverability compared to other shapes, making it suitable for three-wheel vehicles. Therefore, a tadpole shape is an acceptable type of shape for a three-wheel vehicle.

The power actually developed inside the engine cylinder is called indicated power. This power is measured by the pressure exerted on the piston during the combustion process. It represents the total power output of the engine before any losses or inefficiencies are taken into account. Brake power, on the other hand, is the power available at the engine's output shaft, after accounting for losses due to friction and other factors. Frictional power refers to the power lost due to friction within the engine. Therefore, the correct answer is indicated power.

Positive camber refers to the outward tilt of the wheels from the vertical axis when viewed from the front. This means that the top of the wheels is further apart than the bottom. Positive camber is often used to improve stability and handling in certain vehicles, such as off-road or heavy-duty vehicles. It helps to distribute the weight evenly on the tires and improves traction in certain driving conditions.

The allowed traction motor should be a BLDC motor with a peak power not exceeding 4.5 kW. This means that the maximum power output of the motor should not exceed 4.5 kW. This specification is important because it sets a limit on the power that the motor can generate, ensuring that it is compatible with the requirements of the system it is being used in. A motor with a higher peak power could potentially cause issues or be unnecessary for the intended application.

The minimum wheel diameter should be 12 inches. This means that the wheels of a vehicle should have a diameter of at least 12 inches in order to meet the minimum requirement.

The front hoop must not be more than 9.8 inches forward of the steering wheel.

The correct answer is 180 kg. This means that the maximum weight allowed for the Adventure class, without including the weight of the driver, is 180 kg. This weight limit is likely set to ensure the safety and comfort of the passengers, as exceeding this limit could potentially put strain on the vehicle and affect its performance.

The fully-laden solar car must have a minimum ground clearance of 6 inches. Ground clearance refers to the distance between the lowest point of the car and the ground. A higher ground clearance is necessary for a fully-laden car to ensure that it can navigate over obstacles without scraping the bottom of the car or causing damage. A ground clearance of 6 inches provides a reasonable amount of space for the car to clear most obstacles while maintaining stability and safety.

The maximum normal voltage allowed for the Adventure class accumulator is 60 V. This means that the voltage should not exceed 60 V during normal operation. Additionally, the maximum energy allowed for the accumulator is 20 MJ. This means that the energy stored in the accumulator should not exceed 20 MJ. Therefore, the correct answer is 60 V and 20 MJ, as it satisfies both the voltage and energy requirements for the Adventure class accumulator.

The correct dimensions for Adventure class are 100*60*60 inches.

The correct answer is 5 mm. This means that there should be a gap of 5 mm between the restraint and the back of the driver's helmet. This is important for safety reasons, as it allows for proper movement and cushioning in case of impact or sudden stops. A larger gap could result in the helmet not being properly secured and potentially causing injury to the driver.

The diesel cycle consists of one constant pressure process, one constant volume process, and two isentropic processes. In the constant pressure process, fuel is injected and burned at a constant pressure, resulting in an increase in temperature and volume. The constant volume process is the expansion stroke, where the combustion gases expand and do work on the piston. The two isentropic processes are the compression stroke and the exhaust stroke. Overall, the diesel cycle is commonly used in diesel engines, where fuel is ignited by the heat of compression rather than a spark plug.
