Having three frame members provides a strong and secure connection between the bulkhead and the roll hoop, enhancing the overall safety of the vehicle.

The correct answer is Double lug Joint & Sleeved butt Joint. This means that both the double lug joint and the sleeved butt joint should be used for the non permanents joint for roll hoop bracing. The double lug joint provides extra strength and stability by using two lugs or brackets to connect the components, while the sleeved butt joint involves overlapping and welding the ends of the components together, creating a strong and secure joint. Using both of these joint types ensures maximum structural integrity for the roll hoop bracing.

Tires of the same axle may have different temperatures because they are exposed to different levels of friction and heat. The tire on the driver's side may experience higher temperatures due to constant braking and acceleration, while the tire on the passenger's side may have lower temperatures. This difference in temperature can be caused by various factors such as driving habits, road conditions, and weather conditions.

The lower rail/frame member can be considered as a lower side impact member only if it meets the diameter and wall thickness requirements. This suggests that the structural integrity and strength of the member are crucial in order for it to effectively absorb and distribute impact forces during a side collision. The other options, such as the height from the ground, being a single piece member, or being a composite material, do not directly address the necessary characteristics for it to function as a lower side impact member.

The positive steering stops can be placed on either the rack or the upright. This means that they can be located either on the steering rack or on the uprights of the suspension system. The placement of these stops is crucial as they limit the maximum angle to which the wheels can be turned, preventing damage to the steering components and ensuring safe steering operation.

Aluminium tubing should have a wall thickness more than 1.2mm. This is because aluminium tubing is commonly used in various applications where strength and durability are required. A thicker wall thickness helps to increase the structural integrity of the tubing, making it more resistant to bending, deformation, and other forms of mechanical stress. Therefore, in order to meet the necessary strength requirements, aluminium tubing should have a wall thickness greater than 1.2mm.

It is permissible to fabricate the Front Hoop from more than one piece of tubing because there are no restrictions or guidelines mentioned that prohibit the use of multiple tubing pieces. Therefore, it can be assumed that using multiple pieces of tubing to fabricate the Front Hoop is allowed.

The correct answer is that only the tallest driver will be seated in the car during the tilt test. This suggests that the weight distribution of the car is important during the test, and having both drivers in the car may affect the balance. By having only the tallest driver, it ensures that the weight is properly distributed and the test can be conducted accurately.

The front hoop braces must be straight in order to provide maximum stability and support to the structure. Straight braces ensure that the force and weight distribution is evenly spread, preventing any potential weak points or imbalances. This helps to maintain the structural integrity and durability of the front hoop, ensuring it can effectively withstand any external forces or impacts.

The correct answer is "Be avoided. Not allowed." This means that if composite materials are used for structures such as the Front hoop, it is not allowed and should be avoided.

The Impact Attenuator Data Report using the Impact Attenuator Data (IAD) Template must be submitted only if the Impact Attenuator (IA) is being used. This means that if the IA is not being used, there is no requirement to submit the report. The other conditions mentioned, such as purchasing the IA from outside or manufacturing it in-house, or using it for more than one year, do not affect the need to submit the report. The only factor that determines the submission requirement is whether the IA is being used or not.

According to the given statement, all objects, including body panelling and aerodynamic devices, must be rearward of the rear most plane of the front bulkhead and at least 25 mm behind the AIP. The correct answer is false because the statement is incorrect. It should be true that all objects must be rearward of the rear most plane of the front bulkhead and at least 25 mm behind the AIP.

The jacking point needs to be oriented horizontally and perpendicular to the centerline of the vehicle in order to ensure stability and safety while lifting the vehicle. This orientation allows for even weight distribution and prevents the vehicle from tilting or slipping off the jack.

The correct answer is to provide adequate load paths for transverse and vertical loads in the event of off-axis impacts. This means that the methods of attachment must be able to distribute and transfer the forces generated during off-axis impacts to ensure the structural integrity of the IA and the Anti-Intrusion Plate. This is important to prevent any failure or deformation that could compromise the safety of the Front Bulkhead. The other options mentioned in the question, such as documenting the attachment methods in the IA datasheet and outsourcing the attachment, are not directly related to ensuring load paths for off-axis impacts.

The anti intrusion plate must extend at least to the centerline of the front bulkhead tubing in order to effectively protect the chassis from intrusion. This ensures that the plate covers the entire area that is vulnerable to potential impacts or intrusions. By extending to the centerline, the plate provides maximum coverage and reinforcement to the front bulkhead, enhancing the overall strength and integrity of the chassis.
