Welcome to your 2020 Quiz #5 Concerning aerodynamic devices which statement is not compliant to the rules? All aerodynamic devices must be able to withstand a force of 150N A rear wing rearward of the driver head restraint is permitted if it's lower than 0.9m from the ground Aerodynamic devices mounted forward than 800mm from the fronts of the tire are prohibited All aerodynamic devices in front of the front axle and extending further outboard than the most inboard point of the front tire/wheel must be higher than 250mm from the ground 1 out of 10 Your car is the ultimate acceleration machine…… and is able to lift the front tires off the track during the first section of the accelleration event!Your wheelbase is the required minimum, your weight distribution with driver is 70% rear and you are using the latest tires with a friction coefficient of µ=2 (CoF).What is the minimum possible height of your center of gravity of your car to show the mentioned behaviour?Answer in [m], rounded to 0.01 Please use the following format: 12.34 2 out of 10 You do an acceleration run.Your car constantly accelerates with 10m/s². After 10 meters your engine / motor(s) die and deliver no power anymore. Your car then constantly de-accelerates with 0.2 m/s².How far do you make it from the start?Answer in whole [m].Please use the following format: 12.34 3 out of 10 Your car has a suspension geometry with zero caster, camber and toe.The tire contact patch is assumed to be linear, the contact force distribution is assumed to be triangular (see image). How much steering torque applied on the steering wheel is required to move the steering from the center position during standstill?Tire width w: 7 inchControl rod arm e: 95mmPinion meshing diameter d: 34mmWeight of car with driver: 227kgWeight distribution with driver: 48% FrontStatic tire µ: 1.5 (CoF)g = 9.81 m/s²Answer in [Nm], rounded to .1Please use the following format: 12.34 4 out of 10 You build an AutoX track on your testing ground. Which elements are not conformant to the rules? 45° turn with a diameter of 20m and a track width of 2.75m Hairpin turn with an inner diameter of 6m and a track width of 3.5m Slalom with constant spacing of 10m Straight with a length of 70m and a track width of 4m 5 out of 10 You plan a nice display for your race cars in your shopconsisting of platforms suspended on steel tie rods. All parts are delivered as designed, but you notice that the assembly was done differently.Is this a problem? Yes, because the tire rods might be overloaded Yes, because the nuts might be overloaded Yes, because some of the nuts are loaded in the wrong direction Yes, because the ceiling mounts might be overloaded No, alls parts are still bearing their design loads 6 out of 10 Which driving trajectory fits the data shown in the diagram? B C D A 7 out of 10 Which statement regarding the shutdown buttons is false? The shutdown buttons must be connected in series to the low voltage master switch The buttons must be clearly marked by the international electric symbol The minimum diameter of the cockpit mounted shutdown button is 24mm At a minimum, two shutdown buttons must be installed 8 out of 10 What is true regarding the mechanical configuration of the tractive system energy storage? Holes in the container are only allowed if they are necessary for the venting of explosive gas Fasteners to attach pouch cells to the container must comply with rule T10 The mounting of the accumulator cells to the container must withstand 40 g acceleration in vertical direction Vertical walls must be made from steel 0.9mm thick or aluminium 2.3mm thick only 9 out of 10 Your battery pack is built from 4 Stacks of 103 Cells each (103S4P)Each stack has a capacity of 1.20 kWh and an internal resistance of 320 mOhm. If all cells are charged & balanced to 3.80V and behave equally, which current do you draw at 30 kW power output from the pack?Answer in [A] rounded to .1Please use the following format: 12.34 10 out of 10 2019-12-18
