As I wrote in my "ladle calculation", it is not the kinetic energy that is at play: SUR the donkey
I am a tench in calculations on the other hand in system it is a little different this is why apart from any calculation the description of the mechanical system would interest me (wish pile )
It also seems to me that it is the weight at the (very brief) moment of passage of the vehicle that drives the donkey back.
I also wonder if the time of "weighing" on the donkey is sufficient to make the donkey perform a sufficient race.
But I am not stuck enough to calculate the number of cm of penetration according to the resistance of the speed bump of the weight (average) and the speed (average 15km / h?) Of the vehicles at the time of the toll.
What is certain is that no vehicle will park on the donkey, it will only pass over a small fraction of a second with each axle.
Technically it's a hell of a challenge "all weather" for the mechanism to remain in good condition: hot, cold, humidity, runoff, infiltration, salting salt, frost, ice and everything with the same characteristics of thrust, sinking and lifting regardless of the ground temperature which can vary from 0 to 60 degrees approximately
