1. How much current flows when 99 C passes down a wire in 11 s? Give answer in amps as a whole number.

2. Which of these HV- and LV-components have to be fire-retardant? (Multiple Choice)

3. 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

4. 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. 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.

6. Your team is considering two languages, Verilog and VHDL, for programming an FPGA. Which languages could be used?

7. 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)

8. 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

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

10. Which of the following statements is false regarding the difference between Lead-based batteries, Nickel-based batteries and Lithium-based batteries?

1. Calculate the pull force on the plate in Newton. Round to 2 numbers seperated by a point (exanple: 9.13)

2. A ball at a height of 20ft on Earth with a gravitational field strength of 9.81 N/kg, gained 284 J of gravitational potential energy. Calculate the mass of the ball. Give answer to two decimal place in kg.

3.

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. A team is in the process of validating the compliance of the shoulder harness bar used in their car. Choose the part in which their configuration is incompliant:

6. 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

7. The magnitude of the manifold reaction force FK is to be determined. In Newton, integer, no unit in the answer

8. During last year acceleration a top speed of 100 km/h was reached. Due to big improvements in the new drivetrain, the new vehicle reaches a top speed of 120 km/h. The aerodynamics chief has some worries about the stability of the rear wing bracing due to the higher aerodynamics load. Given the geometry below, by how much % does the bearing force in point A change in comparison to last year? (The aerodynamic package did not change and therefore some values can be assumed for both vehicles). Give answer rounded to one decimal place.

CL=3.8     CD=1.2     A=1 m²     rho=1.1 kg/m³     L1=50 mm     L2= 100 mm     H1= 125 mm     H2= 165mm

9. A spring in a car’s suspension has elastic potential energy store 226 J. If the spring constant is 8.1N/mm, find the extension. Give answer in meters to three significant figures.

10. How much current flows when 99 C passes down a wire in 11 s? Give answer in amps as a whole number.
