Umbhobho womoya wefeni ohlukileyo wahlukile kumbhobho womoya osicaba. Umbhobho womoya othe tyaba wenziwe ngomqolo wemingxunya emincinci, enokutshiza ikhethini lomoya ngobubanzi obufana nobomlomo. Umbhobho womoya ophephezelayo unesakhiwo esifanayo kumbhobho wamanzi wefeni, kodwa umlomo womoya unendawo. Ngokubanzi, imilo ye-V efana nombhobho wamanzi ayisetyenziswanga, kodwa i-U iyasetyenziswa. Kungenxa yokuba umoya unokucinezelwa, ke ukuba kusetyenziswa imilo V, ulwabiwo lomoya alunakulinganiswa, kodwa uyilo olumilise u-U olunokuthi luyenze. Esi siphoso.

Umbhobho womoya ophefumlelweyo onokutshiza unokutshiza igesi ecinezelekileyo, umphunga oxinzelelekileyo kunye nolwelo. I-engile yayo yokutshiza ihlala i-70 degrees. Sinokwenza i-angle kwaye sihambe ngokweemfuno zakho. Nceda uzive ukhululekile ukuqhagamshelana nathi.
