FSA/FSG_1

1.A FS car is capable to to drive 10m/s in a circle of unknown diameter. How fast can it go in a circle of equal diameter and 10deg steep curve? The friction coefficient is 1.5 (Neglect aero, suspension and fancy kinematics). Give your answer to m/s in two decimals

2.Pablo wants to build an elevator from his eb018 (160kg). He uses all four wheels and a rope as a frictionless winch. Pablos weight is 70kg and the car power is limited by formula student rules. Assume the car is immediately at full speed.At 100m Pablo gets scared and decides to jump out of the car. It takes him the longest possible(to be rules compliant) time to get out of the car. How deep does he fall? Answer in m without rounding

4. Your vehicle has tires of 385mm diameter. In side view the most upper point of your rear wing has a vertical distance from the ground of 1180mm and a horizontal distance from the rear of your rear tires of 230mm. The distance of the most upper point of your rear wing with the most rear point is 987.61mm. In side view the most upper point of the front wing is located 452mm from the ground. The horizontal distance between the most front point of the front wing and the most upper point is 7.3mm. The most front point of the front located at the minimum allowed distance from the ground. The diastance of the most upper point of the front wing and the front of the front tires is 737.18mm. In also side view (actually always on side view) the horizontal distance between the most rear point of the rear wing and the most front point of the front wing is 2958.3mm and they are on the same horizontal axis,in which the center of wheel axles are. What's the wheelbase of your vehicle? Answer in mm without decimals.

5.The accumulator container is marked with an equilateral triangle sticker meeting ISO 7010-W012. The area of the sticker is 40cm^2. Is the sticker big enough?

6.You are at the competition with your team and you have several sets of tires with you because your team captain loves to change tires. So you use a different set of tires for the practice area than you use at the brake test(1). For the dynamic events you choose one set of dry tires and one set of wet tires you also showed at the inspection, but the weather is changing very often. You start your first race with your dry tires, but during autocross, it starts to rain and you have to change tires for the second run(2). As the weather is pretty bad at the day of endurance, you decide to start with your tires for wet conditions. After 8 rounds the weather gets declared as damp and you want to change the tires during the driver change(3).Is everything rules compliant?

9.Whats the minimum points you can get from dynamic events if you score maximum points on all static events,you had valid runs on both accelaration and skidpad and you didnt participate AutoX. Also you got a penalty at the end of endurance of 2 mins cause of a violation with and advantage for your team. Answer rigid number in points.

10.Your car has a Fan with 300N of thrust. You want to use it for an optimal accel start. You could use the Fan to increase the downforce (90deg vertical mounting), like a normal Turbine and to get more drive force (0deg horizontal mounting) or in between those angles. What is the best mounting angle to get the highest acceleration when the friction coefficient is 1.5? The Fan is not used to provide flow for other parts of the aero. Answer in radians and round to 3rd decimal

11. An accumulator (144s2p) is providing a current of 100A. Each cell has an internal resistance of 2mohm. Assume the accumulator as an ideal voltage source in series with an ohmic resistor and neglect the resistance of wires. What is the thermal power los in the accumulator? Answer ridid number on W.
