Kutheni kukho isibane esinye kuphela esingasemva senkungu?
Kukho inzululwazi yokuba nesibane esinye senkungu esingasemva, esifakwe kwicala lomqhubi, ukuze imoto ikhuseleke ngakumbi ekuqhubeni. Ngokwemigaqo yokufakelwa kweezibane zemoto, kufuneka kufakwe isibane esinye senkungu esingasemva, ngelixa kungekho mthetho unyanzelekileyo wokufakwa kwezibane zenkungu zangaphambili. Ukuba sikhona, isibane senkungu esingaphambili kufuneka sibe zimbini. Ukuze kulawulwe iindleko, ezinye iimodeli ezikumgangatho ophantsi zinokurhoxisa isibane senkungu esingaphambili kwaye zifake isibane esinye senkungu esingasemva. Ke ngoko, xa kuthelekiswa nezibane ezimbini zenkungu ezingasemva, isibane esinye senkungu esingasemva sinokuphucula ingqalelo yesithuthi esingasemva. Indawo yesibane senkungu esingasemva esifakiweyo ifana kakhulu neyesibane sebhuleki, okulula ukuyibhidanisa iintlobo ezimbini zezibane zentloko kwaye kubangele iingozi zokhuseleko. Ke ngoko, isibane esinye senkungu sibonakalisa ngcono ukhuseleko lwemoto.
