The minimum radius a main hoop tube can be bent is 78 mm. This means that the tube must be bent with a radius of at least 78 mm in order to maintain its structural integrity and prevent damage.

2. What is the peak-to-peak voltage value of a single-phase sinuisodal 300V AC RMS signal?

848.53V

832.74V

424.26V

416.37V

519.62V

The peak-to-peak voltage value of a sinusoidal AC signal is twice the amplitude of the signal. The RMS voltage is given as 300V, so the amplitude can be calculated by multiplying the RMS voltage by the square root of 2. Therefore, the amplitude is approximately 300V * √2 = 424.26V. The peak-to-peak voltage is then twice the amplitude, which is approximately 424.26V * 2 = 848.53V.

3. Which value must the current limiting resistors for the each tractive system measurement point have, if the nominal tractive system voltage is 398.8VDC and maximum tractive system voltage is 407.8 VDC?

10k ohm

20k ohm

15k ohm

5k ohm

The current limiting resistors for each tractive system measurement point must have a value of 15k ohm. This is because the current limiting resistors are used to limit the amount of current flowing through the measurement points. The nominal tractive system voltage is 398.8VDC and the maximum tractive system voltage is 407.8VDC. By using a 15k ohm resistor, the current flowing through the measurement points can be kept within a safe range.

11. Substitute the variables A and B with the correct values: All forward facing edges on the bodywork that could impact people, e.g. the nose, must have forward facing radii of at least A. This minimum radius must extend to at least B relative to the forward direction, along the top, sides and bottom of all affected edges.

This rule does not exist, therefore A and B can not be filled with correct values.

A = 38 mm (1.5 inches); B = fifty-five degrees (55°)

A = 38 mm (1.5 inches); B = forty-five degrees (45°)

A = forty-five degrees (45°); B = 38 mm (1.5 inches)

A = 48 mm (1.5 inches); B = forty-five degrees (45°)

The correct answer is A = 38 mm (1.5 inches); B = forty-five degrees (45°). This means that all forward facing edges on the bodywork that could impact people must have a minimum forward facing radius of 38 mm (1.5 inches). This minimum radius must extend to at least forty-five degrees (45°) relative to the forward direction, along the top, sides, and bottom of all affected edges.

The tractive system firewall must be composed of two layers.

The firewall must be mounted to the chassis with at least 4 screws with a minimum size of M4.

The given statement states that the firewall must be mounted to the chassis with at least 4 screws with a minimum size of M4. However, this requirement does not exist for the tractive system firewall. Therefore, this statement is incorrect as it contradicts the given requirements for the firewall.

14. The 'weight transfer' (in N) during cornering is dependent on:

Lateral acceleration, track width, CoG height, vehicle mass

Lateral acceleration, wheel base, CoG height, vehicle mass

Lateral acceleration, wheel base, CoG height

Lateral acceleration, track width

Lateral acceleration, track width, CoG height

The correct answer is Lateral acceleration, track width, CoG height, vehicle mass. Weight transfer during cornering is influenced by several factors. Lateral acceleration refers to the force that pushes the vehicle sideways during a turn, which affects weight transfer. Track width, the distance between the left and right wheels, also plays a role in weight transfer. The height of the vehicle's center of gravity (CoG) affects how weight is distributed during cornering. Finally, the mass of the vehicle determines the overall weight that is transferred. All of these factors interact to determine the amount of weight transfer during cornering.
