5. Consider a digital LVTTL signal from your pedalbox to your main control unit. The length / of the cable inbetween is 5m. Your motor controllers introduce a noise of 0.15 V per meter cable.

1. 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)
2. Your team is considering two languages, Verilog and VHDL, for programming an FPGA. Which languages could be used?
3. Which statements about the travel of the driving pedal is correct

4. 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)
5. 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
6. A thin circular, isolated wire made of copper with radius R lies on a table with its ends connected to a Volt meter. Another, straight wire lies exactly along a diameter of the circular wire, connected to an alternate current source i(t) = I0 sin(wt). The experimental setup is shown in the following Figure:
Which effective voltage Ueff does the Volt meter display? R = 10 cm, maximum current I0 = 1 A, f = 50 Hz. Give your answer in Volts with three decimal places
The magnetic field lines H around the straight, current-carrying wire run in concentric circles, with their centres lying on the wire axis. The field lines thus enter the wire perpendicularly in one half of the circle and leave it perpendicularly in the opposite half. This means that one semicircle of the induction loop is penetrated by the time-varying magnetic flux (t), while the opposite semicircle is penetrated by exactly the opposite flux -(t) for reasons of symmetry. The total flux at any time is zero at all times, which means that no induction voltage and thus no effective voltage Ueff is indicated at any time. The specification of the data in the task was therefore completely superfluous.
7. Which of the following requirements of the brake light assembly must be met to be rules compliant? (multiple choice)

Quiz „General Engineering“
1. 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.
2. An object is fired vertically upwards from the ground at time t = 0 s in still air at a speed of 8.0 m/s.

3. A vehicle with the mass 190kg, wheelbase 1,56m and tyre static radius 222mm is weighed.

Give answer to the nearest whole number in mm
Fb‘ = m*g (at rear axle while front tyres are lifted)

r= radius of tyre

6. 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)
