Kutheni kukho isibane senkungu esinye kuphela esingasemva?
Kukho imeko yenzululwazi yokuba nesibane senkungu esinye ngasemva, esifakwe kwicala lomqhubi, ukwenza imoto ikhuseleke ngakumbi xa iqhuba. Ngokwemimiselo yokufakelwa kwezibane zemoto, isibane esisodwa senkungu sangasemva kufuneka sifakwe, ngelixa kungekho mmiselo osinyanzelo wokufakelwa kwezibane zenkungu zangaphambili. Ukuba kukho enye, isibane senkungu sangaphambili kufuneka sibe zibini. Ukuze kulawuleke iindleko, ezinye iimodeli ezinesiphelo esisezantsi zinokucima isibane senkungu esingaphambili kwaye sifakele isibane senkungu esinye kuphela esingasemva. Ke ngoko, xa kuthelekiswa nezibane zenkungu ezimbini ezingasemva, isibane senkungu esinye esingasemva sinokuphucula ukuqwalaselwa kwesithuthi esingasemva. Isikhundla sesibane senkungu esingasemva esifakiweyo sifana kakhulu nesibane sebrake, ekulula ukubhidanisa iindidi ezimbini zezibane kwaye kubangele iingozi zokhuseleko. Ke ngoko, isibane senkungu esinye kuphela esiluphawu olungcono lokhuseleko lwemoto.
