3. If a sinusoidal voltage signal of 150Hz is applied to it, tell the impedance of a capacitor with a capacity of 50 microFarad?

2.122ohm

21.22ohm

2.374ohm

23.74ohm

The impedance of a capacitor is given by the formula Z = 1/(2πfC), where Z is the impedance, f is the frequency, and C is the capacitance. In this case, the frequency is 150Hz and the capacitance is 50 microFarad. Plugging these values into the formula, we get Z = 1/(2π * 150 * 50 * 10^-6) = 21.22 ohm.

4. Tell the minimum distance between the Main hoop tubes where the Main hoop is connecting to the major structure of the frame.

355mm

380mm

400mm

450mm

The minimum distance between the Main hoop tubes where the Main hoop is connecting to the major structure of the frame is 380mm. This measurement ensures that there is enough space for the Main hoop to securely connect to the frame without compromising its structural integrity. A distance of 380mm provides sufficient clearance for the tubes to be properly joined, ensuring the overall stability and safety of the frame.

5. Which minimum spacing through the air must be maintained between tractive system and GLV parts that are in the same enclosure if the potential between those parts is above 200VDC?

10mm

20mm

30mm

40mm

A minimum spacing of 30mm must be maintained between the tractive system and GLV parts that are in the same enclosure if the potential between those parts is above 200VDC. This spacing is necessary to prevent any arcing or electrical discharge that could occur due to the high voltage, which could potentially cause damage or injury.

6. Via what is the actuation of the throttle not allowed?

Throttle by wire

Rod system

Cable System

Every one of the above is allowed.

Throttle by wire refers to a system where the throttle is electronically controlled rather than through a physical connection like a rod or cable system. In this system, the actuation of the throttle is not allowed through a physical mechanism but is instead controlled electronically. Therefore, throttle by wire is the only option where the actuation of the throttle is not allowed through a physical connection.

7. Which value should the current limiting resistors for each tractive system measurement point have with the maximum tractive system voltage = 398.8VDC?

5kohm

10kohm

15kohm

20kohm

The current limiting resistors for each tractive system measurement point should have a value of 10kohm. This value is suitable for limiting the current in the measurement circuit and ensuring accurate measurements without causing damage to the circuit. Using a higher resistance value could result in inaccurate measurements, while using a lower resistance value could cause excessive current flow and potential damage to the circuit.

8. A hose used to vent a cooling system catch can have a minimum inner diameter of:

1/8 inch

2.54 mm

3 mm

1/32 inch

1/16 inch

The correct answer is 3 mm. This is because the question is asking for the minimum inner diameter of a hose used to vent a cooling system. Out of all the options given, 3 mm is the smallest measurement, indicating the minimum size required for the hose.

9. Pick the wrong statement about Vehicle Status Report and Video.

The video should always be filmed from a 3rd person's view.

It needs to be between 15sec and 30sec long.

The car needs to accelerate from standing still.

The given statement "Teams that hand in a Vehicle Status Report must answer all questions from the organizers within 48 hours after submission of the report" is incorrect. There is no requirement for teams to answer all questions from the organizers within 48 hours after submission of the report.

Explanation

The given statement "Teams that hand in a Vehicle Status Report must answer all questions from the organizers within 48 hours after submission of the report" is incorrect. There is no requirement for teams to answer all questions from the organizers within 48 hours after submission of the report.

10. ________ has to be sent in prior to the FSG competition.

Business Logic Case

Executive Summary

Team Photo

Driving Licence of Driver

The executive summary has to be sent in prior to the FSG competition. The executive summary is a concise document that provides an overview of the business logic case. It includes key information such as the problem statement, proposed solution, market analysis, and financial projections. Sending in the executive summary before the competition allows the judges and organizers to review and evaluate the business idea before the actual event takes place. This helps in streamlining the competition process and ensures that all participants have a fair chance to present their ideas.
