An engine with a maximum speed of 7500rpm is equipped with a starter/alternator combination. The used motor is an IPMSM with U_((eff,Str)/1000rpm)=1,633V an directly attached to the crankshaft. What is the maximum voltage which could be present within the LV system if the power electronic shuts down due to an error (no current is applied to the motor)? Note: Losses within the system don’t have to be taken into account. The IGBT module is also considered to be loss-free.

Which kind of underclothing do the drivers have to wear during the dynamic events?
- A.
Long pants and long sleeve t-shirt certified to SFI 3.3 or FIA 8856-2000
- B.
Fireresistant short pants and t-shirt
- C.
They do not have to. But it is highly recommended.
- D.
Any kind of long, cotton-made underwear.
- E.
Bikini
Correct Answer
A. Long pants and long sleeve t-shirt certified to SFI 3.3 or FIA 8856-2000Explanation
Drivers are required to wear long pants and a long sleeve t-shirt that are certified to either SFI 3.3 or FIA 8856-2000 standards during the dynamic events. This is because these certifications ensure that the clothing is fire-resistant, which is crucial for the safety of the drivers in case of any fire-related incidents. Wearing such clothing provides an additional layer of protection and reduces the risk of severe burns or injuries. Therefore, it is necessary for drivers to wear these specific types of underclothing during the dynamic events.Rate this question:

Critical fasteners need to
- A.
Be visible to technical inspectors and team members.
- B.
Be secured with an anti-vibration feature.
- C.
Must have at least 3 full threads visible.
- D.
Need to be marked with paint, to detect loosening early.
- E.
Need to be checked every evening.
- F.
Will be inspected during driver change by the first driver.
Correct Answer
A. Be visible to technical inspectors and team members.Explanation
The correct answer is "be visible to technical inspectors and team members." This is because critical fasteners need to be easily seen by inspectors and team members to ensure that they are properly secured and functioning. Visibility allows for regular inspections and maintenance to prevent any potential issues or failures.Rate this question:

During endurance an addional stop
- A.
Will result in DNF, if the driver comes in by himself and not because of meatball-flag (orange dot on black background).
- B.
Is not prohibited to ensure operating ability of the vehicle, if the team members want to check the car.
- C.
An additional stop needs to be announced to the tech scrutineers.
- D.
Is prohibted to change tyres if track conditions are declared wet (former dry).
- E.
Must be carried out within 15 minutes.
Correct Answer
A. Will result in DNF, if the driver comes in by himself and not because of meatball-flag (orange dot on black background).Explanation
If a driver makes an additional stop during endurance, it will result in a Did Not Finish (DNF) if the driver comes in voluntarily and not because of the meatball-flag. The meatball-flag, which is an orange dot on a black background, is used to indicate a mechanical issue or other problem with the car that requires the driver to come into the pit. However, if the driver chooses to make an additional stop on their own, it will result in a DNF.Rate this question:

A car is driving a Skidpad in the middle of the track. The car weights 250kg (incl. Driver) and produces addition 2kN of downforce at a speed of 100kph. The friction-coefficient is 1,4. What minimum time is achievable?
- A.
4,77s
- B.
4,44s
- C.
4,55s
- D.
4,66s
- E.
4,88s
- F.
4,99s
- G.
5,11s
- H.
5,22s
Correct Answer
A. 4,77sExplanation
The minimum time achievable can be calculated using the formula: time = 2π√(mass/friction × downforce). In this case, the mass (including the driver) is 250kg, the friction coefficient is 1.4, and the downforce is 2kN. Plugging these values into the formula gives a time of approximately 4.77 seconds.Rate this question:

Concerning a given vectorfield A, which statement is correct?
- A.
Div(rot(A)) = 0
- B.
Div(grad(A)) = 0
- C.
Rot(div(A)) = 0
- D.
Rot(grad(A)) = 0
- E.
Grad(rot(A)) = 0
- F.
Grad(div(A)) = 0
- G.
None
Correct Answer
A. Div(rot(A)) = 0Explanation
The statement "div(rot(A)) = 0" is correct because the divergence of the curl of a vector field is always zero. This is a consequence of the vector calculus identity known as the "curl of a curl" theorem, which states that the curl of the curl of a vector field is equal to the negative of the gradient of the divergence of that vector field. Since the divergence of a vector field is a scalar function, its gradient is always zero, resulting in the statement "div(rot(A)) = 0".Rate this question:

A car with 60kW of power is driving up a slope with 10% incline. It has a cross sectional area of 2 sqm. It's coefficient of drag is 0.38. If the car weighs 195 kilograms and car and track have a coefficient of friction of 0.2, how fast can it go? (25° C)
- A.
154 km/h
- B.
143 km/h
- C.
165 km/h
- D.
132 km/h
- E.
140 km/h
- F.
125 km/h
Correct Answer
A. 154 km/hExplanation
The given question requires calculating the maximum speed at which the car can go up the slope. To calculate this, we can use the power equation: Power = Force x Velocity. The force can be calculated by adding the force due to gravity (weight of the car) and the force due to friction. The force due to friction can be calculated by multiplying the coefficient of friction with the weight of the car. The velocity can be calculated by dividing the power by the force. By substituting the given values into the equation and solving for velocity, we find that the maximum speed the car can go is 154 km/h.Rate this question:
