DOO Penatly in autocross is 2 secs per cone

Re-arrange formula from FSG Rules 2023 D6.3.2

Plug values into formula (don’t forget that Tmax is 1.25x the best time from all teams including penalties)

installation cost: 400.000 EUR
machine cost: 20.000 EUR x 5 years = 100.000 EUR
material cost: 70 EUR x 950 cars = 66.500 EUR
Total cost: 566.500 EUR
Cost per car: 566.500 EUR /950 = 596 EUR

5 / 20

To build your race car you need a part what can be bought on the public market for 400 EUR per piece. Your plan is to sell 950 race cars the next five years. If you will manufacture the part by yourself, you need an investment of 400.000 EUR for the installation. Furthermore, you need to pay 20.000 EUR per year for the machine operator. The material costs are 70 EUR per piece. The machine cannot be sold after the usage. What is the cost of one piece of the own manufactured parts? Give answer as one whole number

Steps:

calculate average time between left circle and right circle for each run
add any penalties to these times
decide on the best time of Team A and Team B
slowest time between these two best times is T_team
fastest time between these two best times gets multipled by 1.25 and is T_max
use formula from FSG Rules 2023 D4.4.3

A thin circular, isolated wire made of copper with radius R lies on a table with its ends
connected to a Volt meter. Another, straight wire lies exactly along a diameter of the
circular wire, connected to an alternate current source i(t) = I0 sin(wt).
The experimental setup is shown in the following Figure:

Which effective voltage Ueff does the Volt meter display?
R = 10 cm, maximum current I0 = 1 A, f = 50 Hz.
Give your answer in Volts with three decimal places

The magnetic field lines H around the straight, current-carrying wire run in concentric circles, with their centres lying on the wire axis. The field lines thus enter the wire perpendicularly in one half of the circle and leave it perpendicularly in the opposite half. This means that one semicircle of the induction loop is penetrated by the time-varying magnetic flux (t), while the opposite semicircle is penetrated by exactly the opposite flux -(t) for reasons of symmetry. The total flux at any time is zero at all times, which means that no induction voltage and thus no effective voltage Ueff is indicated at any time. The specification of the data in the task was therefore completely superfluous.
