The time penalty for an off-course is 10s
An off-course occurs if a slalom gate is missed

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

I am allowed to participate in dynamic events
I am eligible for the design finals
I am only allowed to go to the practice area
My vehicle is completely safe
If I change nothing and nothing breaks, i can not be disqualified for technical reasons
My car is completely rules compliant

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
rear wing is too wide
front wing overall width is too wide
endplate gurneys are generally not allowed
cone slots would have to be movable (illegal movable aero devices)

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?

This is actually the cell voltage
The conversion factor is wrong
The signed-ness is wrong
The can bus is overloaded
The endianess is wrong
