1.Assuming the skid pad event has only two participants, Team A and B: calculate the score rounded to two decimals for the team, which scored the lower amount of points using the following data. Use format 12.34 for your answer and round to two decimals.

2.In your Business Plan Presentation you state the following facts: Your company has fixed costs (overhead) of 295000 EUR per year.The variable costs for each car are at 64100 EUR. How many cars at a price of 66400 EUR do you minimally have to sell to make profit. Give your answer as an integer number

3)Which of the following front bulkhead support structure designs fulfill both rules T3.11 and T3.14.1? Please note: All the shown members follow T3.2.1. Give the answer by selecting the right variants.

4.Calculate the voltage across RL in volt, round the end result to one decimal. Assume all components (Op Amps, diodes, ...) to beideal. GIve your answer in V and round to one decimal.

5.Your CAN network consists of 5 ECUs. The CAN network uses high speed CAN with 500 kbit/s. 5 ECUs want to send a message same time on the bus. ECU 5 wants to send a message with the ID 0x5D6. The figure shows the CAN ID of the messages from theECUs as logical signals (TTL signals between μC and Transceiver) or voltage levels (wiring harness). Which ECU will win thearbitration? Give the answer as one digit, which represents the ECU number.

6.Calculate the resultant force in Point B in Newton (dimensions in the figure are not exactly to scale). Round the result to one decimal.given: F1 = 500 N, F2 = 300 N, a = 175 mm, alpha = 20°. Answer in N and round to one decimal. If you have deviation of +-5 N your answer will be correct.

7.Calculate the coordinate of center of gravity in mm (dimensions in the figure are not exactly to scale). Round your answer to 2decimals.Given is a = 10mm. The origin (x=0,y=0) is at the red dot and the dimensions of the shape are along the positive axes. Assume anevenly distributed area mass. Give your answer in the following format: x,y. Example: if x=12.34 and y=56.78 then use 12.34, 56.78.

8.Calculate the angular resonance frequency ω in rad/s for the shown system. Round the result to one decimal. The mass of thesprings and the mass of the connecting elements should be neglected.Given: m = 45 kg; c1 = 255N/mm; c2 = 2*c1. Give your answer in rad/s and round to one decimal.

9.Calculate the total capacity of the shown electrical circiut in micro Farad. Round the result to one decimal.Given: The capacity of each capacitor is 4 micro Farad. Give your answer in microFarad and round to one decimal.

10. Calculate the angle bewteen the both strings with length l = 300 mm if the centrifugal governor turns with 100 rpm.Assume that the gravitational acceleration is g = 9.81 m/s2 and the strings have no mass and do not stretch. Round the result indegrees and round to one decimal.

11.The official standing at the finish line and waving the finish flag hears the noise (single frequency) of an FS car as it approaches finish line of the acceleration event. After crossing the finish line the single frequency noise of the FS car, when it is driving awayform the official, is a major third lower than initially heard (f1/f2=5/4).At what speed did the vehicle cross the finish line? Assume the speed of sound is c = 340m/s and the speed of the FS car is constantover time. Also assume, that the distance between the official and the longitudinal axis of the FS Car is 0 mm. Give the answer in km/h and round to one decimal.
