1.A car finishes the skidpad event with an average laptime of 5.0 second. The static friction coefficientof the ground and the tire is 0.9. What was the aerodynamic downforce to weight ratio during the run? Assumethat the car is travelling on the centerline of the track. g=9.81m/s²

0.45

0.5

1.35

0.9

2.Which of the listed material can be described with the following fictional mechanical properties? Specific strength(σ[ΜPa]/ρ[g/cm³])=1656, Specific modulus (σ[GPa]/ρ[g/cm³])=57,Failure Strain (%)=1.8

Carbon Fiber Reinforced Polymer

Aramid Fiber Reinforced Polymer

titanium

Steel

3.According to the FS Rules 2019, how many points will a team score eventually on the Cost and Manufacturing Event, if the team is not in the final, the score awarded to a team during the initial judging is 79 points, while the highest score awarded to any team not participating in the final is 91 points?

86.8

82.5

4.At least how many TS voltage measurements have to be in the electrical system?

5.Which of the following dynamic disciplines will be organized first time in 2019 at FS East?

Driverless Skidpad

Driverless AutoX

AutoX

Trackdrive

6.What does the yellow and red stripped flag mean during Endurance and AutoX Event?

Mechanical black flag. The driver must pull into the driver change area for a mechanical inspection of the vehicle, something has been observed that requires a closer inspection.

The driver must be prepared to overtakea slower car on the racing line

The track is slippery or something is on the racing surface that should not be there. The driver must be prepared for evasive maneuvers to avoid the situation.

The driver must pull into the driver change area for discussion with the officials concerning an incident. A time penalty may be assessed.

7. Can a team be eliminated from the Engineering Design Event by the judges, if every document of theirs was accepted and they are presented at the Engineering Design Event?

Yes, if the judges consider the vehicle to be in unfinished state

Yes, if the judges consider the number of the team members present at the discussion insufficient.

No, if a team is present at the event, the judges are obligated to evaluate theis performance.

Yes, if the team did not pass any scrutineering prior.

8.Which parameters are not required to calculate the operating temperature of a conductor in open air.

9. Our vehicle completes the Acceleration Event. Its velocity is 126km/h, when it crosses the finish line. How much time did it need to complete the run, if we assume, that its acceleration is constant during the run?

4.56s

3.86s

4.28s

10. You are competing on the Endurance Event. Unfortunately one of the throttle pedal return springs is already broken, but the car operates well. In the long straight the other retunr spring breaks too but the driver doesn't recognize it, and the throttle pedal get stuck at 100%. At the end of the straight, the driver reaches a slalom and pushes the break with medium force. What happens after that?

The breaks are ineffective to slow down the car while the motors are producing full power, driver looses control over the car, hit all cones at high speed and tries to deactivate TS by pushing the cockpit killswitch.

TS may remain active, the vehicle can go through the slalom but won't be able to gain speed anymore.

BSPD immediately shut down the TS as the driver touches the break pedal.

The motors, and therefore the racecar, immediately stop at the end of the straight.

11. In which Cost Report Document does the team need to list the research and developement costs?

in neither of the Cost Report Documents

In the CBOM

In the Cost Explanation File

In th DBOM

12. Which of the following requirements is a must for all types of vehicles, when moving the vehicle on the competition site other than on practice or competition tracks.

Detached master switch

Two team members walking on either side of the vehicle

A registered driver wearing the required driver equipment as defined in T13.3 except for helmet, arm restraints and balaclava having full control of steering and braking

Vehicles must be pushed at a normal walking pace by means of a red pushbar, equipped with a fire extingusher

13. If a thin long fibre's diameter is reduced, which of its properties from the following will increase?

Stiffness

Strength

Young Modulus

Peak force at failure

The circular Dynamic Platform at ZalaZone has 1% slope from North to South. The diameter of the Platform is 300m. If a ball is released on the highest point of the Platform (North), from standstill state, what will be the speed of the ball at the lowest point of the Platform(South)? Consider the ball rolls directly from the highest point to the lowest point. Rolling Resistance is 0. Mass of the ball is 200g. G=10m/s²

5.897 km/h

7.7459 km/h

7.7459 m/s

5.897 m/s

Phase 2

Phase 3

Phase 4

Phase 1
