Umboniso wemveliso:
Intsimbi ejikelezayo yintsimbi eqinile ye-cylindrical, ububanzi bayo bunokuthi buyilwe ngobukhulu obuhlukeneyo ngokweemfuno zemveliso.Inkqubo yokucubungula ibandakanya ukuqengqeleka okushushu, umzobo obandayo, ukubumba kunye nonyango lobushushu kunye nezinye iindlela.Phakathi kwabo, ukutshisa okutshisayo yinkqubo esetyenziswa ngokuqhelekileyo, enokuvelisa intsimbi ejikelezileyo kunye nobubanzi obukhulu.Inkqubo yokudweba ebandayo inokuvelisa i-diameter encinci kunye nokuchaneka okuphezulu kwentsimbi ejikelezayo.
