Olona phawu lubalaseleyo lofakelo lwemilomo yefeni ethe tyaba kukuba izalisa imilomo ekufuphi kwindawo yokutshiza malunga ne-30% yendawo yokugubungela. Kwangelo xesha, ulwazelelo lokutshiza kunye nomgca othe tye zi-5 ° -15 ° ezingabizi kakhulu, zenza usasazo ngokubanzi lokuhanjiswa kokuhamba okufanayo, oko kuyanelisa ngakumbi kwaye kuphuculwe. Ukusetyenziswa kwentloko yokubekwa kwezixhobo zokudlulisa ngokuthe tyaba. Ukubala izithuba zemibhobho yefeni ethe tyaba, ungabhekisa kule fomyula ilandelayo:
