Which measurement voltage will be applied during IMT for a car with a system voltage of 275V?
Correct Answer
C. 500
Explanation
During Insulation Measurement Testing (IMT) for a car with a system voltage of 275V, a measurement voltage of 500V will be applied. This higher voltage is necessary to test the insulation resistance of the car's electrical system effectively. By applying a voltage higher than the system voltage, any potential faults or weaknesses in the insulation can be identified and addressed.
2.
In which case will you be punished for exceeding power and voltage limitation?
Correct Answer
C. Using 82kW for 500ms continously
Explanation
Using 82kW for 500ms continuously will result in exceeding the power limitation. The given power value of 82kW is within the power limitation, but if it is used continuously for 500ms, it may cause the power to exceed the allowed limit. Therefore, in this case, exceeding the power limitation will result in punishment.

A damper assembly (1000$) is missing in your BOM. Your car`s cost is 18000$, minimum cost is 15000$ and maximum cost is 25000$.How many points will you loose if you have a judge from Michigan?
Correct Answer
B. 5
Explanation
If a damper assembly worth $1000 is missing from the Bill of Materials (BOM), it means that the cost of the car will increase by $1000. The minimum cost of the car is $15000, so with the missing damper assembly, the cost will be $16000. The maximum cost of the car is $25000, so with the missing damper assembly, the cost will be $26000. Since the car's cost is $18000, it falls within the range of $16000 and $26000. Therefore, the judge from Michigan will deduct 5 points.

An electric consumer is connected to 230 V alternating voltage wall socket. You measure a current of 10A and a power of 2000W.Calculate apperent power S and reactive power Q.
Correct Answer
A. S=2300VA; Q=1135,8 VA
Explanation
The apparent power (S) is calculated by multiplying the voltage (230V) by the current (10A), which gives 2300VA. The reactive power (Q) is calculated by taking the square root of the apparent power (2300VA) squared minus the power (2000W) squared, which gives 1135.8VA. Therefore, the correct answer is S=2300VA; Q=1135.8VA.

Which answer regarding the change of tires is wrong?
Correct Answer
A. Judges have the possibility to make adjustments to the lap times, if track condition altered during a event and teams had to use different tires
6.
Which of the statements below about charging is wrong?
Correct Answer
B. The container must have a label with the team name and the ESA`s pHone number
Explanation
The statement "The container must have a label with the team name and the ESA's phone number" is correct. This means that the container used for charging must be labeled with the team's name and the phone number of the ESA (presumably a safety authority or organization). This labeling ensures that the container can be easily identified and contacted if there are any issues or emergencies related to the charging process.

What are the requirements for the space for technical inspection stickers?
Correct Answer
D. A space 75 mm tall x 150 mm wide (3” tall x 6” wide) must be available.
Explanation
The correct answer is that a space 75 mm tall x 150 mm wide (3” tall x 6” wide) must be available. This means that there is a specific requirement for the space for technical inspection stickers, and it must be a certain size in order to accommodate the sticker.

Explanation
A team gets a penalty of 0.25 seconds added for one cone down or out at Skid-Pad.
9.
The driver can (re)activate the tractive system when ....
Correct Answer
D. ... a torque encoder implausibility occured
Explanation
When a torque encoder implausibility occurs, it means that there is a discrepancy or inconsistency in the readings from the torque encoder. The torque encoder is responsible for measuring and transmitting the torque applied to the tractive system. If there is an implausibility in the readings, it could indicate a fault or malfunction in the torque encoder. To address this issue, the driver can reactivate the tractive system, possibly by resetting or recalibrating the torque encoder, to ensure accurate torque measurements and proper functioning of the tractive system.

The rise time (from 10% to 90%) of the capacitor voltage of a given one stage low pass RC network is 5.00ms. What are possible values for R and C
Correct Answer
D. R = 1500Ω; C = 1517nF
Explanation
The rise time of a capacitor voltage in an RC network is determined by the product of the resistance (R) and the capacitance (C). A smaller resistance value will result in a faster rise time, while a larger capacitance value will result in a slower rise time. In this case, the given rise time of 5.00ms suggests that a smaller resistance value is required. Among the options provided, the combination of R = 1500Ω and C = 1517nF gives the closest rise time to the given value. Therefore, R = 1500Ω and C = 1517nF are the possible values for the given one stage low pass RC network.
