Indlela yokuhlola iziphethu?
Kuzo zonke izakhi zokumiswa, indlela elula yokuhlola isimo sezinto zensimbi zasentwasahlobo isesimweni sezinhlobo ezihlukahlukene zeziphethu.
Ungabona indawo ethambekele noma "eyehlisiwe" ngokusobala yomzimba wemoto ongalayishiwe, emi endaweni eyisicaba evundlile. 
iso lenyama. Lesi simo sifakazela ukuthi ingxenye eyodwa noma zonke zasentwasahlobo zemoto zilahlekelwe ukunwebeka ngenxa yezinguquko zesakhiwo sangaphakathi noma ngenxa yokulimala kwemishini. Ezimotweni zabagibeli, iziphethu zamakhoyili zisetshenziswa kakhulu njengezinto zensimbi zasentwasahlobo. Bangakwazi ukudlulisa amandla e-axial kuphela, ngakho-ke avame ukusetshenziswa ekumisweni okuzimele. Uma kucatshangelwa ukuma kwemithombo ye-cylindrical, umehluko wenziwa phakathi kwemithombo ye-cylindrical, conical kanye ne-barrel. Izici zemithombo enjalo nazo zingahluka, i.e. ukuncika kokuchezuka kumandla asetshenzisiwe. Ngaphandle kwemithombo enesici esiqondile, iziphethu ezinesici esiqhubekayo zisetshenziswa, ezitholakala esimweni se-cylindrical helical spring sibonga ngocingo lwe-variable cross section.
Iziphethu ze-Helical azikho ngaphansi kokulungiswa, kodwa kuphela ukuqinisekiswa, okuhlanganisa ukuqhathanisa ubude bentwasahlobo yamahhala nobude besiphethu ngaphansi komthwalo ochazwe ngokuqinile. Lapho ukuchezuka kudlula imingcele evumelekile, intwasahlobo kufanele ishintshwe. Ngokuvamile kunconywa ukuthi kushintshwe zombili iziphethu ku-ekseli efanayo, ngisho noma eyodwa kuphela yazo inokugqoka ngokweqile.
