The drawings of the car included in the design report can be manual
Correct Answer
A. True
Explanation
The explanation for the given correct answer is that the drawings of the car included in the design report can indeed be manual. This means that the drawings can be hand-drawn or created by using traditional artistic techniques, rather than being generated digitally or using computer-aided design (CAD) software. Manual drawings can provide a more artistic and personal touch to the design report, showcasing the creativity and skill of the designer.

Can a team have more than one captain ?
Correct Answer
A. Yes
Explanation
Yes, a team can have more than one captain. In certain situations, especially in sports or group activities, there may be multiple individuals who possess leadership qualities and can effectively guide the team. Having multiple captains can distribute the responsibility and workload, allowing for better coordination and decision-making within the team. It also promotes a sense of inclusivity and ensures that different perspectives and strengths are represented in the leadership role.

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?
Correct Answer
A. 17.824A
Explanation
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.

Which measurement voltage will be used during the insulation measurement test for a carwith a maximum tractive system voltage of 260V?
Correct Answer
D. 500V
Explanation
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.

How many max. Members are allowed in the driver change area for an EV?
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.
11.
Points deducted for a missing material in BOM?
Correct Answer
E. 1
Explanation
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.

Minimum area moment of inertia of Side impact structure, front bulkhead, roll hoop bracing,driver’s restraint harness attachment is—
Correct Answer
C. 6695mm^4
Explanation
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.

One layer of firewall, facing the tractive system side, must be made of aluminum with athickness of at least _____. This part of the tractive system firewall must be grounded according to ______.(fill the correct option in the statement)
Correct Answer
A. 0.5mm, EV 4.3
Explanation
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. Additionally, this part of the tractive system firewall must be grounded according to EV 4.3.

Total energy absorbed by the impact attenuator must meet or exceed:
Correct Answer
D. 7350J
Explanation
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.

All equivalency calculations must prove equivalency related to steel grade:
Correct Answer
B. SAE/AISI 1010
Explanation
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.

What is the standard for "Motor vehicle brake fluid"?
Correct Answer
A. J1703
Explanation
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.
