2. Which of these HV- and LV-components have to be fire-retardant? (Multiple Choice)
See FSG rules 2023: EV5.3.4, EV5.4.6, EV5.5.12
3. Which statements about the travel of the driving pedal is correct
FSG Rules 2023: T11.8.1, T11.8.5
4. Your team is considering two languages, Verilog and VHDL, for programming an FPGA. Which languages could be used?
5. Which of the following statements about LV battery packs with lithium based chemistry other than LiFePo4 is not true?
See FSG rules 2023 T11.7.7
6. How long will it take to discharge C1 below 60V using the following constant current sink if it is initially charged at 565V? (MOSFET’s VGSth: 4V) Give answer to two decimal places in secs.
Circuit’s current: MOSFET will operate in linear zone, close to the activation voltage. Therefore, as VGSth is 4V, VS can be taken as 8V. From these 8V and the 47R current limiting resistor, the discharge current of the circuit will be 8/47->0,17A As the constant current discharge of a capacitor depends on capacity, as V=i·t/C-> t=V·C/i=(565-60)·0,0012/0,17=3,56s
7. For this Wheatstone Bridge based NTC temperature measurement circuit, which is the lowest voltage measurement (VAB) that is possible to obtain at 60ºC? (NTC B: 3435 +/-1%) Give answer in Volts rounded to two decimal points.
8. A capacitor with a capacitance of 100 μF is currently charged to a voltage of 199.8V. How much additional energy is needed to charge it to a voltage of 301.4V. Give answer to 4 significant figures in Joules
W = 0.5 * C * U^2
∆W = W_end – W_start = 0.5 * C ((U_end)^2 – (U_start)^2)

1. A lorry contains an engine with a power of 2.78 J/s. The lorry drives for 36 mins. Calculate the energy transferred in kJ rounded to three decimal places.
P = E/t = W/t
2. A hall with a floor area of 500 m² is to be equipped with underfloor heating, which will be operated at an average temperature of 33°C.
What percentage of the floor area must be used as heating surface in order to ensure an indoor temperature of 18°C when the outside temperature is -15°C?
Result in m^2 as an integer
3. Calculate the force Fc working at point C.
Rax = 4kN, Ray = 10 kN
Rbx =5 kN, Rby = 8 kN
Moment equation around point D:
0 = -Fc x 1m + Rby x 2.5 m – 60 kN x 4 m + Ray x 5.5 m
Fc = -165 000 N
Fc = – 165 kN
4. A lorry contains an engine with a power of 0.255 W. The lorry drives for 51 s. Calculate the energy transferred in Joules and round to one decimal places.
5. Answer in MJ, round to one decimal number (example 45.7), no unit in the answer
6. You would like to drink a cup of very hot coffee with milk early in the morning, but you are in a hurry and have only 5 minutes until you have to leave for work. At which time after brewing should you add the cold milk to the coffee and stir in order to decrease the temperature of the mixture as much as possible: a) 0 minutes (immediately), b) 2 minutes, or c) 4 minutes? Suppose that the stirring can be done instantaneously and that you need the last one minute for drinking.
brew temperature C = 80 ◦C, temperature of milk = M = 10 ◦C, room temperature 0 = 20 ◦C, volume of coffee VC = 300 ml, volume of milk VM = 100 ml, specific heat capacity of coffee cC = 4180 J/(kgK), specific heat capacity of milk cM = 3500 J/(kgK).
Please enter only the letter of the corresponding answer
The driving „force“ for the cooling of the coffee is the temperature difference between the warm coffee and the environment (room temperature), which leads to an exponential drop in coffee temperature. The temperature difference is greatest immediately after brewing. The later we stir in the milk, the lower the coffee temperature has already dropped. On the other hand, lowering the temperature by the milk becomes smaller the longer we wait. So we let the coffee cool down on its own for as long as possible in order to bring about the temperature reduction by the cold milk at the end. The greatest possible cooling is therefore achieved when the milk is added after 4 minutes.

8. The previous season you could recuperate only 25% of your initially stored energy, but this season a big improvement in your drivetrain allows you to recuperate 63% of the initially stored energy. Knowing that you had 9.6 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 to one decimal place.
E_new = E_old * (1+0.25)/(1+0.63)
