The ground clearance of an FSAE vehicle has to be (at least):
- A.
  
  25.4 mm
- B.
  
  50.8 mm
- C.
  
  Zero if e.g. Sliding skirts are used
- D.
  
  Sufficient
Correct Answer
C. Zero if e.g. Sliding skirts are used

Explanation
The ground clearance of an FSAE vehicle has to be zero if sliding skirts are used. Sliding skirts are a type of aerodynamic device that extends down to the ground to reduce drag. In order for the sliding skirts to function properly, they need to be in constant contact with the ground. Therefore, the ground clearance needs to be zero to ensure that the skirts are effectively reducing drag.

To prevent vehicle roll during cornering the roll center has to be:
- A.
  
  At the level of the sprung mass CoG
- B.
  
  At the level of the vehicle CoG
- C.
  
  At 1/3 of the unsprung mass CoG height
- D.
  
  At 2/3 of the vehicle CoG height
- E.
  
  On the road surface
- F.
  
  Below the road surface
Correct Answer
D. At 2/3 of the vehicle CoG height

Explanation
The roll center needs to be at 2/3 of the vehicle's Center of Gravity (CoG) height in order to prevent vehicle roll during cornering. This is because placing the roll center higher than the CoG creates a moment that opposes the rolling motion, providing stability to the vehicle. Placing it lower than the CoG would create a moment that amplifies the rolling motion, leading to instability. Therefore, positioning the roll center at 2/3 of the vehicle's CoG height is the most effective way to prevent vehicle roll during cornering.

As per the Rulebook the rule for Side Impact Structures is applicable for
1. Cockpit 2. Drivers Leg 3. Accumulator 4. Tractive system
- A.
  
  1,2
- B.
  
  1,3,4
- C.
  
  1,2,3
- D.
  
  2,3,4
- E.
  
  1,3
Correct Answer
B. 1,3,4

Explanation
The Side Impact Structures rule is applicable for the Cockpit, Accumulator, and Tractive system. This means that these three components must meet certain requirements and standards in order to ensure safety in the event of a side impact. The rule does not apply to the Driver's Leg, so it is not included in the correct answer. Therefore, the correct answer is 1,3,4.

Identify the type of fit, H7/g6 :
- A.
  
  Sliding fit
- B.
  
  Transition fit
- C.
  
  Clearance fit
- D.
  
  Interference fit
Correct Answer
A. Sliding fit

Explanation
A sliding fit refers to a type of fit where there is a small amount of clearance between the mating parts, allowing them to slide or move easily against each other. In the case of H7/g6, H7 represents the hole tolerance and g6 represents the shaft tolerance. This combination suggests that the hole is slightly larger than the shaft, creating a sliding fit where the parts can slide smoothly against each other.

- B.
  
  72 kg
- C.
  
  75 kg
- D.
  
  77 kg
- E.
  
  80 kg
Correct Answer
D. 77 kg

Explanation
The preferred weight of the driver for T-Inspection and vehicle simulation is 77 kg. This weight is likely considered ideal for these activities, possibly due to factors such as maintaining balance and stability while operating the vehicle, ensuring proper weight distribution, and minimizing potential safety risks.

- E.
  
  Glycol Antifreeze or Water wetter only
- F.
  
  All of the above
Correct Answer
D. Plain Water or Oil only

Explanation
The correct answer is Plain Water or Oil only. This means that either plain water or oil can be used as a coolant for the tractive system. Other options such as water wetter, glycol antifreeze, or a combination of different coolants are not allowed for the tractive system.

Any portion of the roll bar, roll bar bracing or frame which might be contacted by the driver’s helmet must be covered with a minimum thickness of ___________ mm ?

Correct Answer
12

Explanation
The correct answer is 12 because any portion of the roll bar, roll bar bracing, or frame that might be contacted by the driver's helmet must be covered with a minimum thickness of 12 mm. This is to ensure the safety of the driver in case of any impact or collision. The thickness provides a sufficient barrier to prevent any direct contact between the helmet and the roll bar, reducing the risk of injury to the driver's head.

It is essential to have an eye bolt for Lap belt mounting
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
Having an eye bolt for lap belt mounting is essential because it provides a secure attachment point for the lap belt. The eye bolt is designed to handle the forces exerted on the belt during a collision or sudden stop, ensuring that the belt remains in place and effectively restrains the occupant. Without an eye bolt, the lap belt may not be properly secured, increasing the risk of injury in the event of an accident. Therefore, it is important to have an eye bolt for lap belt mounting.

It is essential to have an eye bolt for Anti-submarine belt mounting
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
Having an eye bolt for anti-submarine belt mounting is not essential. An eye bolt is a type of fastener with a looped head that is used to secure objects or provide attachment points. However, for anti-submarine belt mounting, other types of fasteners or attachment points can be used instead of an eye bolt. Therefore, the statement is false.

Maximum 70% of the brake travel can be used for Regenerative braking
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
The statement is false because maximum 100% of the brake travel can be used for regenerative braking. Regenerative braking is a system that allows the electric motor to act as a generator, converting the kinetic energy of the vehicle into electrical energy. This energy is then stored in the battery for later use. Therefore, there is no limitation on the percentage of brake travel that can be used for regenerative braking.
