لو تسمحولى اشارك معاكم بتفسير


Sorry for writing in English. I took me half an hour to write the above line alone.
It is a known fact that every car to have what we call natural frequency which is dependent on car mass and suspension stiffness. If you manage to apply vertical force or (excitation from road profile) to the car wheels close to this frequency you end up having the car increased in its vertical heave motion (bounces) till actually leaves the road. This is called resonance. This is what probably happened with you. The car was traveling around 100 Km/hr which causes the bridge segments to pulsate the suspension with a frequency close to natural frequency (resonate the car system) around 1 Hz. This will cause the car to start bouncing up and down till it actually leaves the road and have a brief “fly”. This can happen to any car, you just need to be at the right speed on the right bumpy bridge. It is easier to happen on the way down a bridge due to downhill road profile which makes the flying occurs earlier. For more info on this topic please visit…

Hope this helps, thanks for sharing, be safe out there. Reduce speed on any bridge with bumpy spacers.

جميل جدا

تعرف اني كتير كنت باحس بالفكرة دي بس ماوصلش بيا التفكير لفكرة resonance مع اني كنت باحس بيه

يعني ساعات في اللانسر و السيراتو و البولو كمان تلاقي العربية على طريق وحش ..و تاخد مطب و هووب يادوبك واحدة وراها و هووووب و تالتة و هووووووووب أفرمل بقى لأننا شكلنا هانتسوح ...

و ساعات تمشي في طريق مليان مطبات و تاخدهم ورا بعض و تحس بشوية دربكة و خلاص.

تحياتي للتوضيح
