Isikhala Three-ntathu we kulomhlaba

isikhala Three-ntathu uyisibonelo weJiyomethri zomhlaba esiphila. Three-ntathu, ibizwa ngokuthi ngenxa incazelo yakhe oluhambisana ezintathu iyunithi zithwala kokuba izinkomba ubude, ububanzi nobude. Bezibona isikhala ngakuthathu namanje okhulayo ngesikhathi isencane kakhulu futhi kuhlobane ngokuqondile kusebentisana yomuntu. I okuqonda wakhe ukujula kuncike ikhono lokuqonda okubonakalayo emhlabeni futhi ikhono ukuhlonza Ubukhulu ezintathu ngosizo izinzwa.

Ngokusho geometry ahlaziye, isikhala ngakuthathu iphoyinti ngalinye ochazwa esibonisa nenani, ngokuthi izixhumanisi ezintathu. Ukudidiyela izimbazo okuyizinto perpendicular nomunye, iphuzu empambana bakha umsuka, kokuba value zero. Isikhundla yingasiphi isikhala isihlobo kuchazwe izimbazo ezintathu kokuba ezahlukene value kwamanani ngamunye isikhawu kusengaphambili. isikhala Three-ntathu ngamunye amaphuzu ayo ebizwa ngokuthi izinombolo ezintathu elihambisana ibanga ukusuka reference iphuzu ngamunye Ukudidiyela-eksisi kwaze kwaba seqophelweni ezimpambanweni zomgwaqo indiza kusengaphambili. Kukhona futhi enjalo Ukudidiyela uhlelo njengoba izinhlelo eyindilinga futhi cylindrical.

Ngo-algebra eqondile, umqondo wokumeda ngakuthathu ochazwa nomqondo ukuzimela komugqa. isikhala okungokomzimba ngakuthathu ngoba ukuphakama into akuxhomekile ububanzi nobude. In ulimi Linear Algebra Isikhala ngakuthathu ngoba ngamunye iphuzu ngabanye ke kungaba azimisele kusukela inhlanganisela zithwala ezintathu ezingasuthi yemigqa zizimele kusukela kwenye. Kulesi ekwakhiweni, umqondo isikhala-isikhathi ukubaluleka ezine-ntathu, ngoba esikhundleni iphuzu ezinkathini ezihlukahlukene zesikhathi akuxhomekile indawo yayo emkhathini.

Ezinye izakhiwo elinendawo isikhala ezintathu-ntathu, kachesvenno zihlukile izikhala ezisebusweni ezinye izinhlangothi. Ngokwesibonelo, ifindo ngiboshwa intambo, itholakala endaweni ephansi kulinganiswa. Iningi kwemithetho yemvelo ezihlobene Ubukhulu ngakuthathu isikhala, isibonelo, ephambene nomthetho sikwele. Emkhathini ngakuthathu kungenzeka isikhala mgudumbili, omunye-ntathu zero-ntathu, ngenkathi ngokwayo kuthathwa njengengxenye imodeli isikhala ezine-ntathu.

Isotropy isikhala ingenye izakhiwo zayo eziyinhloko e Mechanics classical. isikhala Isotropic libizwa ngoba lapho ujikelezisa inkomba Uhlaka ngasiphi angle ngokungenasizathu sishintsha Imiphumela nesilinganiso kungukuthi kwenzekani. Umthetho ukulondolozwa umfutho emincane kusekelwe izakhiwo isotropic isikhala. Lokhu kusho ukuthi esikhaleni kuzo zonke iziqondiso bayalingana futhi akukho definition ezithile isiqondiso nge ezimele wesimethri axis. Isotropy has ezifanayo kodwa ngesikhathi esifanayo ngokomzimba kuzo zonke izindawo kungenzeka. Ngakho, isikhala isotropic - kungcono elinjena izakhiwo ngokomzimba we okuyinto musa kuxhomeke isiqondiso.
