Calculate the Area Moment of Inertia of the following triangle shape element. Dimensions are given in cm. Answer at m^4 in 3 decimals.
Teams A and B compete in trackdrive. The lap length is 420.69m and their corrected used energy is equivalent to the caloric content of 400 TRIPLE WHOPPERs® and 900 Big Macs® without cheese, respectively. Their lap times times are (from first to last) 171.32, 153.42, 123.96, 120.1, 112.9, 102.4, 95.89, 93.65, 97.54, 96.32 for A and 133.56, 125.25, 112.78, 107.53, 103.91, 97.23, 95.83, 90.28, 96.62, 99.69 for B (in seconds). What is their point difference in Trackdrive & Efficiency? Give the number in absolute value, rounded to 2 decimals. The Tmin overall is 989.21s with a corrected energy usage of 0.885 times of team A’s. Assume the nutrition information was obtained from the official company datasheets.

Elon Musk takes his dirty old pickup truck for a ride in town after a crazy mountain trip. He makes sure that there is enough energy left in his battery pack and then he heads to the car wash and there he checks the tire pressure. The indicator shows 320 kPa. Is it good enough, he wonders as he wants no more laughters about his track after his broken car windows. He decides to ask his favorite FSAE team, Aristurtle, to assist him real quick. What's the value of the rolling resistance Fr of his 3 tones cybertruck when he styles in town at 25m/s. Give your answer in N, in the first decimal.
Choose the correct statements
If only 1 ASR is named by the team, he may not be a driver
If a team member is in the cockpit, the autonomous steering & braking systems must be mechanically disconnected.
Since FSG2017, the electrical inspection is carried out in a different place than the accumulator inspection.
During any autonomous mission, you must be able to brake manually.
Transformer with ratio 1:20 secondary to primary windings. Calculate the current in the primary side of the transformer if there is a 10 Ohm load in the secondary side. Give your answer in Amperes in the second decimal.
Choose the correct statements
After the RES has been triggered to stop the vehicle, it should not be able to steer further.
A team can only have one inspection responsible person.
When the ASSI is yellow continuous, it’s the next transition is either yellow or blue flashing.
You can have an intermediate state in your AS state machine if it’s well documented and its necessary for the functional safety of the vehicle.
We have a grey body from an unknown material that obeys Stefan - Boltzmann Law. If this material’s heat transfer per unit time (W) is half of a black hole’s surface of the same size, shape and at the same absolute temperature. Calculate the heat emission due to thermal irradiation in nW/m^2 for a square shaped “grey body” at 5 Kelvin given that the Stefan Boltzmann constant is σ=5,6703*10E-8 W/m^2*K^4. Give your answer to the second decimal.
Choose the correct statements:
The magnetic flux in the number of lines of force in Teslas
In a purely inductive circuit, voltage leads current by 90 degrees
A series RL Filter circuit with the output across the inductor will result in a low pass type filter.
