Electric Solar Vehicle Championship-2020

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.

The teams are required to provide ergonomics as per the SAE (Society of Automotive Engineers) standards for the 95th percentile male and 5th percentile female. This means that the design and layout of the equipment or workspace should accommodate the body dimensions and capabilities of individuals who are larger and smaller than the average population respectively.

The fully-laden solar car must have a minimum ground clearance of 6 inches. Ground clearance refers to the space between the lowest point of the vehicle and the ground. A higher ground clearance is necessary for off-road driving and to prevent the car from scraping against uneven surfaces. A fully-laden car means that it is carrying a load, which can lower the height of the vehicle. Therefore, a minimum ground clearance of 6 inches ensures that the car can safely navigate various terrains without compromising its undercarriage.

The minimum wheel diameter should be 12 inches. This means that the wheels of the object in question should have a diameter of at least 12 inches. This requirement could be based on factors such as stability, clearance, or compatibility with other components.

The allowed traction motor for this scenario should be a BLDC motor with a peak power not exceeding 4.5 kW. This means that the motor should have a maximum power output of 4.5 kW or lower. Any motor with a higher peak power would not be within the allowed specifications.

The Battery Management System (BMS) is indeed compulsory in a battery pack. It is responsible for monitoring and controlling the battery's performance, ensuring its safe and efficient operation. The BMS regulates the charging and discharging process, protects against overcharging and over-discharging, balances cell voltages, and provides important information about the battery's state of charge and health. Without a BMS, the battery pack would be prone to damage, reduced lifespan, and safety hazards. Therefore, it is necessary to have a BMS in place for proper management and optimal performance of the battery pack.

The maximum allowable steering system free play is 7 degrees. This means that there should not be more than a 7-degree movement in the steering system before it starts to engage and turn the wheels. Any free play beyond this limit can result in a lack of control and responsiveness in the steering system, which can be dangerous while driving.

The statement is true because yaw refers to the rotation of a vehicle around its vertical axis. When a vehicle brakes, it may experience a yaw motion, but it should not exceed 30 degrees. Yawing excessively can lead to loss of control and potentially cause accidents. Therefore, it is important for a vehicle to maintain stability and not yaw more than 30 degrees under braking.

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

The driver must have a total vision range of 200º to ensure maximum visibility and awareness of their surroundings while driving. This wide range of vision allows the driver to see objects and potential hazards from various angles, reducing the risk of accidents and improving overall safety on the road. Having a 200º vision range enables the driver to have a comprehensive view of the road ahead, as well as the ability to check blind spots and monitor the movement of vehicles and pedestrians in their vicinity.

Teams in the Adventure class are not allowed to place panels on the roof or over the head of the driver.

The correct answer is 90 mm, 165.1 mm. This means that the minimum tread width of the tire should be 90 mm, while the maximum tread width should be 165.1 mm. The tread width refers to the distance between the outer edges of the tire's tread. It is important to have a minimum and maximum tread width specified to ensure that the tire provides proper traction and stability on the road.

A tadpole shape is allowed in a three-wheel vehicle. A tadpole shape refers to a vehicle design where there are two wheels in the front and one wheel in the back. This configuration provides better stability and maneuverability compared to a delta shape, which has one wheel in the front and two wheels in the back. Therefore, a tadpole shape is preferred and allowed in three-wheel vehicles.

The correct answer is 60 V and 20 MJ. This means that the maximum normal voltage allowed for the Adventure class accumulator is 60 volts, while the maximum normal energy capacity is 20 megajoules.

The minimum wall thickness of the material used in the chassis is 1 mm. This means that the thinnest part of the chassis should be at least 1 mm thick. This requirement ensures that the chassis has enough strength and rigidity to support the vehicle's structure and components. A thicker wall provides better structural integrity and durability, making it suitable for the demanding conditions and loads that a chassis may experience during operation.

The correct answer is 0.10%. In the case of steel material used in the chassis, a minimum carbon percentage of 0.10% is required. This is because carbon is an important component in steel that enhances its strength and hardness. However, too much carbon can make the steel brittle, so a balance needs to be maintained. A carbon percentage of 0.10% is sufficient to provide the necessary strength and durability for the chassis without making it overly brittle.

There must be three kill switches in the vehicle to ensure safety and control. These switches are designed to immediately shut down the vehicle's engine and electrical systems in case of emergencies or to prevent unauthorized use. Having three kill switches provides redundancy and ensures that the vehicle can be quickly and effectively immobilized when necessary.

When the top of the wheel is tilted outward, it is called positive camber. Positive camber means that the top of the wheel is angled away from the vehicle's centerline. This can be beneficial for stability and handling in certain situations, such as when cornering or carrying heavy loads. Positive camber can also help with tire wear, as it promotes even distribution of weight across the tire tread. However, excessive positive camber can lead to uneven tire wear and reduced handling performance.

If the vehicle goes out of track during the Endurance event, the team will face a penalty of 20 points. This means that they will have 20 points deducted from their overall score. Going out of track is likely considered a mistake or deviation from the designated course, which leads to a penalty. The severity of the penalty may vary depending on the rules and regulations of the specific competition, but in this case, it is determined to be 20 points.

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. If the distance is too short, it may not provide adequate support for the head and neck in case of a collision. If the distance is too long, it may cause discomfort and restrict visibility. Therefore, 800 mm is the ideal distance for the hip point to the top of the head restraint.

The correct answer is 12*2*0.1968 inches. This is because the dimensions of the jack point must be specified as 12 inches in length, 2 inches in width, and 0.1968 inches in height.

The correct answer is 4 inches because a suspension with a total travel of 4 inches would provide adequate cushioning and absorption of shocks and bumps while maintaining stability and control. This amount of travel is commonly used in off-road vehicles and mountain bikes to ensure a smooth and comfortable ride over rough terrain. It strikes a balance between flexibility and rigidity, allowing for efficient energy transfer and preventing bottoming out or excessive bouncing.

The correct answer is 178 mm & 229 mm. This is because the shoulder harness mounting point should be within this range to ensure proper positioning and effectiveness of the harness in restraining the occupant during a crash. Any mounting point outside of this range may compromise the safety of the occupant.

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

The correct answer is 25 mm. This refers to the required gap between the restraint and the back of the driver's helmet. This gap is important to ensure proper safety and comfort for the driver. A 25 mm gap allows for enough space for the driver's head to move and rotate without restriction, while still providing adequate support and protection from the restraint. A smaller gap could cause discomfort and restrict movement, while a larger gap may compromise the effectiveness of the restraint system.
