What is the minimum tread depth for rain tires?
-
2.4mm (3/32 inch).
-
1.6mm (2/32 inch)
-
0.8mm (1/32 inch)
-
3.2mm (4/32 inch)
Correct Answer
A. 2.4mm (3/32 inch).Explanation
The minimum tread depth for rain tires is 2.4mm (3/32 inch). This depth is necessary to ensure proper traction on wet surfaces and prevent hydroplaning. A shallower tread depth would not be able to channel water effectively, leading to reduced grip and increased risk of accidents in rainy conditions. A deeper tread depth may not be necessary and can cause excessive noise and wear on dry roads. Therefore, 2.4mm (3/32 inch) is the optimal minimum tread depth for rain tires.Rate this question:

A steady DC current is flowing through a coil with an inductance of 248mH. The stored energy in the magnetic field is 431J. By how much does the current have to be increased, if the stored energy should be increased by 300J?
-
76.78 A
-
76.77 A
-
76.79 A
-
17.820 A
-
9.767 A
Correct Answer
A. 76.78 AExplanation
The stored energy in an inductor is given by the formula 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. Plugging these values into the formula, we can solve for the initial current. Then, we can use the same formula with the new desired stored energy of 731J to solve for the increased current. The difference between the two currents will give us the amount by which the current needs to be increased, which is approximately 76.78 A.Rate this question:

Which one is not a positive locking mechanism according to the rules?
-
Lock washer
-
Safety wire
-
Nylon lock nut
-
Nylon lock nut
Correct Answer
A. Lock washerExplanation
A lock washer is not a positive locking mechanism according to the rules because it does not provide a reliable and secure means of preventing loosening or rotation of a fastener. While a lock washer can create tension and friction to help prevent loosening, it is not as effective as other options such as safety wire or nylon lock nuts, which are specifically designed to securely lock fasteners in place.Rate this question:

Maintenance plugs must separate the internal cell segments such that the separated cell segments contain a maximum static voltage of less than 120VDC.
-
Maintenance plugs must separate the internal cell segments such that the separated cell segments contain a maximum energy of 12MJ
-
Maintenance plugs requiring tools to separate the segments will not be accepted
-
Maintenance plugs must include a positive locking feature which prevents the plug from unintentionally becoming loose.
-
Maintenance plugs must be made of a material with a specific electrical resistance of less than 300 mOhmMeter
-
The function of maintenance plugs may also be fulfilled by additional contactors.
-
Maintenance plugs must be used whenever the accumulator containers are opened for maintenance and whenever accumulator segments are removed from the container.
Correct Answer
A. Maintenance plugs must separate the internal cell segments such that the separated cell segments contain a maximum energy of 12MJExplanation
The statement that is wrong is "Maintenance plugs must separate the internal cell segments such that the separated cell segments contain a maximum energy of 12MJ." This is incorrect because there is no requirement for maintenance plugs to separate cell segments based on energy levels. The other statements are all correct and provide necessary requirements for maintenance plugs, such as voltage limits, tool requirements, positive locking feature, electrical resistance, and usage during maintenance and segment removal.Rate this question:

Endurance Tire changing - what is true?
-
If I elect to change to wet tires, I may do so during the driver change
-
Wheel Guns' driven from compressed air/gas are prohibited
-
If I elect to change to dry tires, the time for changing is not included in my endurance time
-
For changing tires, up to four team members(excluding drivers) are allowed to work on the car
Correct Answer
A. If I elect to change to wet tires, I may do so during the driver changeExplanation
The correct answer states that if the driver elects to change to wet tires, they may do so during the driver change. This means that the driver can choose to switch to wet tires while they are being replaced by another driver. This implies that the driver change is a convenient time for the tire change, allowing for a seamless transition without wasting additional time.Rate this question:

Which force in rearward direction must the driver's head restraint, its attachment and mounting withstand?
-
At least 890 Newton.
-
At least 750 Newton.
-
At least 510 Newton.
-
At least 1280 Newton.
Correct Answer
A. At least 890 Newton.Explanation
The driver's head restraint, its attachment, and mounting must withstand a force of at least 890 Newton in the rearward direction. This force is necessary to provide adequate protection to the driver's head and neck in the event of a rear-end collision or sudden deceleration. A lower force, such as 750 Newton or 510 Newton, would not provide sufficient protection, while a force of 1280 Newton would be excessive and potentially uncomfortable for the driver.Rate this question:

In steady-state cornering of an understeering car, the lateral acceleration causes the front wheels to slip sideways to a greater extent than the rear wheels. To develop the lateral force at the front wheels to maintain the radius of the turn the driver has to...
-
Increase the steering angle
-
shift the CoG forward
-
Increase the acceleration
-
Adjust the brake balance rearward
Correct Answer
A. Increase the steering angleExplanation
In steady-state cornering of an understeering car, the front wheels slip sideways more than the rear wheels due to the lateral acceleration. To maintain the radius of the turn, the driver needs to increase the steering angle. By increasing the steering angle, the front wheels can generate more lateral force, allowing the car to maintain the desired turn radius. This helps to compensate for the understeer and keep the car on track during the cornering maneuver.Rate this question:

Which charging strategy should be used for a Li-Ion accumulator ?
-
Pulse Charge
-
Delta-T
-
Constant Voltage
-
CC-CV
-
Delta-Peak
Correct Answer
A. CC-CVExplanation
CC-CV charging strategy should be used for a Li-Ion accumulator. This strategy involves two stages of charging - Constant Current (CC) and Constant Voltage (CV). In the CC stage, the battery is charged with a constant current until it reaches a certain voltage limit. Once the voltage limit is reached, the charger switches to the CV stage where the voltage is kept constant while the current gradually decreases. This strategy ensures that the battery is charged efficiently and safely, preventing overcharging and damage to the battery.Rate this question:
