A car is driving a Skidpad in the middle of the track. The car weights 250kg (incl. Driver) and produces addition 2kN of downforce at a speed of 100kph. The frictioncoefficient is 1,4. What minimum time is achievable?
4.65s
4.77s
4.37s
4.33s
4.82s
5.01s
4.69s
A ball (mass m) is attached to a wall with a spring (spring constant c). A force F(t) is applied to the ball in the direction away from the spring. Calculate the transferfunction G(s) = X(s)/F(s), asuming x(t) is the lengthening of the spring an there is neither friction nor gravity to be considered.
G(s) = 1/(m*s^2+c)
G(s) = 1/(m*s-c*s^2)
G(s) = m*s+c
G(s) = m*s+c
G(s) = 1/(m*s+c)

0.002%
1.11%
0.5%
0.2%

The EBS release point must be marked by a red arrow of 100 mm length (shaft width of 20 mm) with “EBS release” in white letters on it.
All deactivation points must be in proximity to each other, easily accessible without the need for tools/removing any body parts/excessively bending into the cockpit.
The EBS may be part of the hydraulic brake system.
The EBS must only use passive systems with mechanical energy storage.
The vehicle must be equipped with an EBS, that must be supplied (but not power supplied) by LVMS, ASMS, RES and a relay which is supplied by the SDC.
The use of push-in fittings is prohibited.
