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.

25.2 m/s
22.5 m/s
81.3 km/h
70.0 km/h
79.7 km/h

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

How many different tires are allowed on a car?

All tires on the vehicle must be of the same manufacturer and compound but may have different sizes
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 one axle must be of the same manufacturer, compound and size
All tires on the car must be of the same manufacturer, compound and size
Tires are not regulated

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

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

Which of the following tubes is not allowed as the stated frame member (regardless of implementation/mounting/etc.)?

35mm x 1.2mm magnesium square tube as front bulkhead support (E=44 GPa)
32mm x 2.5mm round aluminium tube as front roll hoop bracing (E=70 GPa)
25.4mm x 2.4mm seam welded round steel tube as main hoop
1" x 0.083" seamless drawn round steel tube as shoulder harness mounting bar

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

An off-course can be avoided if the driver re-enters the track at or before the point he left it
An off-course occurs if a slalom gate is missed
An off-course during the skidpad event leads to a DNF for that run
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

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

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?

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

What are the responsibilities of the faculty advisor at FSA?

none
Officially receiving trophies during the award ceremony
Doing the on-site team registration
Accompanying the team's car through scrutineering
