To build your race car you need a part what can be bought on the public market for 450 EUR per piece. Your plan is to sell 1200 race cars the next five years. If you will manufacture the part by yourself, you need an investment of 400.000 EUR for the installation. Furthermore, you need to pay 20.000 EUR per year for the machine operator. The material costs are 50 EUR per piece. The machine cannot be sold after the usage. What is the cost of one piece of the own manufactured parts? Give answer as one whole number

16 / 20

In the event of unsportsmanlike conduct, 25 penalty points will be deducted from the team’s overall score. A second violation will result in an additional 100 penalty points deducted from the team’s overall score.

Steps:

  • calculate average time between left circle and right circle for each run
  • add any penalties to these times
  • decide on the best time of Team A and Team B
  • slowest time between these two best times is T_team
  • fastest time between these two best times gets multipled by 1.25 and is T_max
  • use formula from FSG Rules 2023 D4.4.3

Quiz „Electrical“

1 / 10

Your head of powertrain has found a battery cell with excellent specifications and yet cheap. He decides upon a 142s2p accumulator configuration using the cells with a capacity of 5.8 Ah. The manufacturer specifies an internal impedance of 1.5 mOhm. However, after a while you notice the cells are of horrible quality and their real capacity varies significantly leading to an unbalanced accumulator.

He performed experiements to find an approximation of the cells SoC relation to their open-circuit voltage (EMF) as shown in the following figure:

Assume due to imbalance, exactly half of the accumulators cells are at 40% SoC and half at 80% SoC. What current will be drawn at the maximum allowed power usage? Give answer in Amps to nearest whole number

2 / 10

Three inductors are connected as shown in the following figure:

Given that L1 = 2L2, find L1 and L2 such that the equivalence inductance is L = 0.7 H.
Give your answers in Henry, rounded to three decimal places separated by a comma (L1, L2)

3 / 10

Which of the following requirements of the brake light assembly must be met to be rules compliant? (multiple choice)

4 / 10

The previous season you could recuperate only 27% of your initially stored energy, but this season a big improvement in your drivetrain allows you to recuperate 69% of the initially stored energy.  Knowing that you had 6.3 kWh of energy in your accumulator during the last season, how much energy must your new accumulator have, if you assume, that it’s the same length and speed? Give answer in kWh

5 / 10
