FS Poland Registration Quiz 2024

According to Formula Student Rules 2024, Hydraulic System is determined as High Pressure, when system generates pressure:

What is the power measured at the output shaft of the gearbox, which is coupled to the internal combustion engine with the given parameters for constant RPM powered by the fuel described below.
- Fuel specific energy = 47,30 [MJ/kg]
- Fuel density = 720 [kg/m^3]
- Air density = 1,29 [kg/m^3]
- Engine type: single cylinder, four stroke internal combustion naturally aspiratedspark plug indirect injection gasoline engine
- Engine volume = 500 [ccm]
- Volumetric efficiency = 80%
- Engine RPM = 9600
- Air to Fuel Stoichiometric Mass Ratio = 14,7:1
- Engine efficiency = 40%
- Gearbox power loss = 5 [kW]
- Gearbox ratio = 1,25
Assume the complete combustion of the fuel and 100% efficiency in conversion of fuel energy to useful energy.

Calculate the rear wheel speed of the FS car, when crossing the finish line of the Formula Student Poland acceleration event knowing that:
- Its acceleration event time is 4 seconds
- the car is RWD
- the car is symmetrical
- it produces constant longitudinal acceleration through the whole course and when passing the finish line
- aerodynamic drag and downforce are negligible
- g = 9,81 [????/sec^2]
- car and driver mass m = 250 [kg]
- wheelbase WB = 1550 [mm]
- centre of gravity height CGh = 250 [mm]
- static front weight distribution of the car with driver WD = 45%
- tires rolling radius Re = 0,2 [m]
- We assume linear tire model where longitudinal slip stiffness Cκ of the rear tires is directly proportional to their vertical load Fz(rear tire). It is described as slip-stiffness coefficient Cx below:
Cx = Cκ/Fz(rear tire) = 20
Note:
-SAE slip ratio definition used, NOT the terra-mechanics.
-Fz(rear tire) > 0

Two teams are competing in Skid Pad Event on FSP 2024, they have their second run. Both vehicles are running in the middle of the track.
- Car A has average coefficient of friction on both circles µA=1,32 [-], car B has average coefficient of friction on right circle µBr=1,51 [-] and on left circle µBl=1,27 [-].
- Both vehicles have their maximum speed in steady state conditions and have full contact patch with the track.
- Which team is faster and what is the final run time difference according to procedure between those teams after finish Skid Pad event.
- Assume that aerodynamic resistance and downforce are negligible and g=9,81 m/sec^2.
Round the calculations and answer to hundredths.

The crystal structure denoted by A2 is a structure:

Devices D1 and D2 are connected to a common High-speed CAN bus (ISO 11898-2) with matching settings:
- FCAN (after prescaler) = 8 [Mhz]- Tseg1 (Prop Phase 1) = 13
- Tseg2 (Phase 2) = 2
At T0, node D1 starts frame transmission (standard ID = 0x435, DLC = 1, Data = 0x55). At T1 until T2 lines CAN_H and CAN_L were shorted.
What would be a behavior of D1 for given timing relations?
-T0 = 0;
-T1 = 2 us
-T2 = 4 us

At T0 = 0, logic input (V1) switches from logic low V (Low) to logic high V (High).
Logic gate A1 is supplied from 5,0 [V] rail.
All elements are considered to be ideal. Calculate the exact time when C1 capacitor voltage (VC1) reaches 5,0 [V] level, with given:
- V (Low) = 0 [V],
- V (High) = 5,0 [V],
- V (SUP) = 12,0 [V],
- V (CC) = 15,0 [V],
- V (EE) = -15,0 [V]
The result should be given in milliseconds [ms].

A cargo ship has left the port of Gdansk at a constant speed. The captain decided to increase the speed on open water. What is the expected draft (the distance between the waterline and the keel) change of the ship when the velocity is increased and steady state is reached, assuming laminar flow?

If distance of one lap during Endurance race on "Autodrom Slomczyn" racetrack is equal 1200 meters, and yours two last laps (e.g. 6th and 7th laps) had the same time equal 2 minutes and 31 second, Your Team:

Assuming that the start and finish lines during ACC event are marked by blue cones, and 75 meters line between them is designated by orange cones, calculate:
According to the FS-Rules 2024, how many orange cones are needed for the ACC track?
Note: Give the answer as the number with no spaces or other symbols.
