Izonga malini uma ungeqi umkhawulo wejubane?
Ukweqa umkhawulo wejubane njalo kusho izindleko ezengeziwe zomshayeli wemoto. Kodwa-ke, akukhona nje ngezinhlawulo, njengakwi Ukwandisa isivinini semoto kudla uphethiloli omningi... Futhi lokhu kuchazwa yimithetho ye-physics, ngoba imoto ilwa hhayi kuphela nokushayisana kwamasondo, kodwa futhi nokuphikiswa komoya.
Amafomula ezesayensi akhona kudala aqinisekisa lezi zimangalo. Ngokusho kwabo, ukumelana kuyanda njengomsebenzi wejubane le-quadratic. Kanye ne uma imoto ihamba ngejubane elingaphezulu kwe-100 km / h, iningi likaphethiloli osetshenzisiwe kungenxa yokumelana nomoya.
Ochwepheshe baseCanada banqume ukubala inani likaphethiloli eliya ngqo "emoyeni" lemoto yedolobha ehlangene, i-crossover yomndeni kanye ne-SUV enkulu. Kuvele ukuthi uma ushayela ngejubane lika-80 km / h no izimoto ezintathu zilahlekelwa cishe ngama-25 hp. emandleni weyunithi yakho yamandla, ngoba izinkomba zazo cishe ziyafana.
Konke kushintsha kakhulu ngesivinini esikhulayo. Ngejubane lika-110 km / h, imoto yokuqala ilahlekelwa ngu-37 hp, eyesibili - 40 hp. kanti eyesithathu - 55 hp. Uma umshayeli ethuthukisa i-140 hp. (isivinini esiphezulu esivunyelwe emazweni amaningi), bese kuba izinombolo 55, 70 no-80 hp. ngokulandelana.
Ngamanye amagama, ukwengeza isivinini esingu-30-40 km / h, ukusetshenziswa kukaphethiloli kukhuphuka izikhathi eziyi-1,5-2. Kungakho ochwepheshe beqiniseka ukuthi umkhawulo wejubane wama-20 km / h awugcini nje ngokuhambisana nemithetho yezokuphepha nokuphepha, kodwa futhi nangokonga uphethiloli.
