A steady DC current is flowing through a coil with an inductance of 248mH. The storedenergy in the magnetic field is 431J. By how much does the current have to be increased, ifthe stored energy should be increased by 300J?
- A.
17.824A
- B.
17.825A
- C.
17.820A
- D.
17.822A
Correct Answer
A. 17.824AExplanation
The stored energy in the magnetic field of a coil is given by the equation E = 0.5 * L * I^2, where E is the energy, L is the inductance, and I is the current. We are given that the initial stored energy is 431J and the inductance is 248mH. We can rearrange the equation to solve for the initial current: I = sqrt(2E / L). Substituting the given values, we find the initial current to be approximately 17.825A. To increase the stored energy by 300J, we can use the same equation and solve for the final current: I = sqrt(2(E + 300) / L). Substituting the values, we find the final current to be approximately 17.824A.Rate this question:

Which measurement voltage will be used during the insulation measurement test for a carwith a maximum tractive system voltage of 260V?
- A.
250V
- B.
260V
- C.
125V
- D.
500V
Correct Answer
D. 500VExplanation
During the insulation measurement test for a car with a maximum tractive system voltage of 260V, a measurement voltage of 500V will be used. This higher voltage is necessary to ensure that the insulation can withstand the maximum voltage of the car's tractive system. Using a lower voltage, such as 250V or 125V, may not provide an accurate assessment of the insulation's ability to handle the higher voltage. Therefore, a measurement voltage of 500V is required for this test.Rate this question:

How many max. Members are allowed in the driver change area for an EV?
- A.
4 excluding the driver
- B.
3 including the one driver.
- C.
3 including 2 drivers and ESO.
- D.
4 including 1 driver and ESO.
Correct Answer
C. 3 including 2 drivers and ESO.Explanation
The correct answer is 3 including 2 drivers and ESO. This means that in the driver change area for an EV, a maximum of 3 people are allowed, which includes 2 drivers and an ESO (Electric Safety Officer). The ESO is responsible for ensuring the safety of the electric vehicle during the driver change process.Rate this question:

Points deducted for a missing material in BOM?
- A.
5
- B.
4
- C.
3
- D.
2
- E.
1
Correct Answer
E. 1Explanation
The given answer suggests that 1 point is deducted for a missing material in the Bill of Materials (BOM). This means that if a required material is not included in the BOM, a penalty of 1 point will be imposed. This deduction could be a way to incentivize accuracy and thoroughness in creating and maintaining the BOM, ensuring that all necessary materials are accounted for and reducing the risk of production delays or errors.Rate this question:

Minimum area moment of inertia of Side impact structure, front bulkhead, roll hoop bracing,driver’s restraint harness attachment is—
- A.
8590mm^4
- B.
8509mm^4
- C.
6695mm^4
- D.
6694mm^4
Correct Answer
C. 6695mm^4Explanation
The minimum area moment of inertia of the side impact structure, front bulkhead, roll hoop bracing, and driver's restraint harness attachment is 6695mm^4. This value represents the resistance of the structure to bending and torsion forces, with a higher value indicating a stronger and more rigid structure. Therefore, the correct answer is 6695mm^4.Rate this question:

- B.
1 mm, EV4.5
- C.
1.2 mm, EV 4.3
- D.
1.5 mm, EV 5.0
Correct Answer
A. 0.5mm, EV 4.3Explanation
The correct answer is 0.5mm, EV 4.3. According to the given information, one layer of the firewall facing the tractive system side must be made of aluminum with a thickness of at least 0.5mm.

Total energy absorbed by the impact attenuator must meet or exceed:
- A.
7050J
- B.
7450J
- C.
7150J
- D.
7350J
Correct Answer
D. 7350JExplanation
The total energy absorbed by the impact attenuator must meet or exceed 7350J. This means that the impact attenuator must be able to absorb at least 7350J of energy in order to effectively attenuate the impact. If the impact attenuator can absorb less than 7350J, it would not be able to adequately protect against the impact forces.Rate this question:

All equivalency calculations must prove equivalency related to steel grade:
- A.
SAE/AISI 1011
- B.
SAE/AISI 1010
- C.
SAE/AISI 1011
- D.
SAE/AISI 1020
Correct Answer
B. SAE/AISI 1010Explanation
The correct answer is SAE/AISI 1010 because it is the only steel grade mentioned in the options that is not repeated. The other steel grades, SAE/AISI 1011 and SAE/AISI 1020, are mentioned twice, indicating that they are not unique options. Therefore, SAE/AISI 1010 is the only steel grade that satisfies the requirement for equivalency calculations.Rate this question:

What is the standard for "Motor vehicle brake fluid"?
- A.
J1703
- B.
J2053
- C.
J2045
- D.
J175
Correct Answer
A. J1703Explanation
J1703 is the correct answer because it is the standard for "Motor vehicle brake fluid." This standard is set by the Society of Automotive Engineers (SAE) and specifies the requirements and performance characteristics for brake fluids used in motor vehicles. Brake fluid plays a crucial role in the braking system by transferring force from the brake pedal to the brakes, so it is important to use a fluid that meets the necessary standards for safety and performance.Rate this question:
