When you pass technical inspection (all Stickers) it means:

My car is completely rules compliant

I am eligible for the design finals

I am only allowed to go to the practice area

If I change nothing and nothing breaks, i can not be disqualified for technical reasons

My vehicle is completely safe

I am allowed to participate in dynamic events

Your battery pack is built from 3 Stacks of 112 Cells (112S3P), each stack has a capacity of 1.70 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 35kW power output from the pack?

During charging you monitor the cell temperatures by tapping the BMS CAN Bus. The Temperature is transmitted as 16-bit unsigned integer (0.00229 °C/bit). Looking at the data the temperatures look somewhat implausible (see picture below) - what went wrong most likely?

What is false regarding an Off-Course (OC) during endurance?

An off-course during the skidpad event leads to a DNF for that run

An off-course occurs if a slalom gate is missed

An off-course occurs if a vehicle is outside the track boundary with all four wheels

The time penalty for an off-course is 10s

An off-course can be avoided if the driver re-enters the track at or before the point he left it

The Frontwing of your car is attached to the frontbulkhead using four 6mm dowel pins in single shear. What is the maximum allowed deceleration peak in the impact attenuator test if you are testing without the frontwing and its mounting? (T2.20.3/Method b) taumax(Pin)=150N/mm^2

Imagine you’re running AutoX in FSA 2016. You need to limit your speed because of the following corner. What is the fastest can go at the crest/edge and still land before the beginning of the braking zone? + h = 0.25m + s = 5m + g = 9.81m/s² + Consider the car a point mass; Ignore aerodynamic effects.

Your self-developed electronic control module needs 200ms to safely shut down and write back data into nonvolatile memory. How big would the power regulator output capacitance need to be at least to do that in the event of a unexpected shutdown (GLV Master switch turn-off), given that: + The device needs a constant current of 120mA + The regulated voltage is 5V + The CPU will brown-out at 3.8V + There is no reverse-flow back into the supply

Which of the following statements about the legality of the car below is true? + track width = 2500mm + car track = 1700mm + cone height = 280mm + rear wing height = 2100mm + roll hoop height = 2200mm Image (c)TU Munich

the structure around the cone slots is too high

cone slots would have to be movable (illegal movable aero devices)

rear wing is too wide

front wing overall width is too wide

endplate gurneys are generally not allowed

What is the minimum score for the third place in the Business Plan finals (with three finalists) ?

How many different tires are allowed on a car?

All tires on one axle must be of the same manufacturer, compound and size

Tires are not regulated

All tires on the car must be of the same manufacturer, compound and size

The vehicle may have different tires on all four corners but the configuration must be the same as presented during tech inspection.

All tires on the vehicle must be of the same manufacturer and compound but may have different sizes
