Kureba Bane Mbere ya byose, reba coefficient de frais. Coefficient de friction igena feri yibanze ya feri ya feri. Hejuru cyane bizatera ibiziga gufunga, gutakaza ubuyobozi bwicyerekezo no gutwika padi mugihe cyo gufata feri. Niba ari hasi cyane, intera ya feri izaba ndende cyane; Umutekano, feri ya feri bizatanga ubushyuhe bwihuse mugihe cya feri, cyane cyane mugihe cyo gutwara umuvuduko mwinshi cyangwa feri yihutirwa, coefficient de fraux de fraux izagabanuka mugihe cy'ubushyuhe bwinshi; icya gatatu, reba niba ari byiza, harimo kumva feri, urusaku, umukungugu, nubushyuhe. Umwotsi, impumuro idasanzwe, nibindi, nibigaragaza bitaziguye imikorere yo guterana amagambo; bine reba ubuzima, mubisanzwe feri irashobora kwemeza ubuzima bwa kilometero 30.000.
Guhitamo bibiri: Icya mbere, ugomba guhitamo feri yimodoka yakozwe nuwabikoze bisanzwe, hamwe numero yimpushya, coefficient de coiffure, ibipimo ngenderwaho, nibindi, kandi agasanduku kagomba kuba gafite icyemezo, numero yumusaruro, itariki yo gukoreramo, nibindi. ; icya kabiri, hitamo kubungabunga umwuga Baza umunyamwuga kuyishiraho.
