Ulimi lwesiShayina luthakazelisa kakhulu. Igama elifanayo lingaba nemiphumela ehlukene uma lisetshenziswa ezimeni ezahlukene. Isibonelo, igama elithi "shui bao" lisho ukungabi nandaba nokulahla abanye. Kunganwetshwa futhi kusho ukuthi umbhangqwana uyaxabana futhi uhlukane ngenxa yokungaboni ngaso linye. Leli gama lisetshenziswa kakhulu kumamotho.
Ukulahlwa kwesikhwama kuyincazelo yephutha yamamotho ajikelezayo enxeba, okubhekisela kumphumela wokuwohloka kwe-radial ngaphandle kwesiphetho esisongayo se-rotor ngenxa yesivinini esikhulu. Uma sazi okuthile mayelana nama-rotor motors amanxeba, singathola ukuthi kunemikhawulo ethile ngesivinini salolu hlobo lwemoto. Kusukela enanini lezigxobo, kunamamotho amaningi anezigxobo ezingu-6 noma ngaphezulu, okusho ukuthi isivinini sawo esilinganiselwe sincane; abanye abakhiqizi bezimoto bazokwenza ama-rotor motors anezigxobo ezi-4, kodwa inqubo yokukhiqiza iyinkimbinkimbi, futhi ukujika kwe-rotor kufanele kuhlolwe ukuthembeka kwesivinini esingaphezu kwesivinini.
Ukukhiqizwa kwangempela nokuqinisekisa kubonisa ukuthi i-rotor eqinile ephendukayo inamandla anamandla okuvimbela iphakheji ukuthi ingalahliwe kune-rotor ethambile ephendukayo; ngaphezu kwalokho, ukulungiswa okudingekayo, ukubopha, ukuvanisha kanye nezinyathelo zokuphulukisa iziphetho ezisongayo yizici ezibucayi kakhulu. Yiqiniso, uma idivayisi yokunciphisa isivinini ingeziwe ngesikhathi sokusebenza kwemoto, le nkinga izoxazululwa.

Isizathu esiyisisekelo sokuphonswa kwephakheji umphumela we-centrifugal
Into eyenza ukunyakaza okuyisiyingi, ngenxa ye-inertia yayo, ihlale inomkhuba wokundiza igudle isiqondiso se-tangent sesiyingi. Lapho amandla angaphandle ahlangene enyamalala ngokuzumayo noma enganele ukunikeza amandla aphakathi nendawo adingekayo ukuze kunyakaze isiyingi, azosuka kancane kancane asuke phakathi nendawo. Lesi simo sibizwa ngokuthi i-centrifugal phenomenon.
Ngesikhathi sokusebenza kwe-motor, ingxenye ngayinye yengxenye ye-rotor ihamba ngokunyakaza okuyisiyingi enkabeni ye-motor shaft. Ngokusho kobudlelwane phakathi kwejubane namandla aphakathi nendawo ekunyakazeni okuyindilinga, lapho isivinini sikhulu, amandla amakhulu e-centrifugal.
Okuvame ukubonakala empilweni imiphongolo yokuwasha yomshini wokuwasha, ukwenza uswidi kakotini, njll. Izilawuli zejubane ze-Centrifugal, abahloli be-centrifugal, okomisa i-centrifugal, ama-centrifugal precipitators, imiphongolo yokuwasha yomshini wokuwasha, ukwenza uswidi kakotini, imishini yokuhlunga uhlamvu lwemali oluzenzakalelayo, i-discus kanye nemincintiswano yokuphonsa isando emiqhudelwaneni esebenzayo yokuncintisana, njll.
Yonke into inobuhle nobubi bayo. Ngenxa yamandla e-centrifugal, ezinye izingozi zingase zenzeke, zidale ukulimala ezimpilweni zabantu. Ezimotweni ezishayela emigwaqweni evundlile, amandla aphakathi nendawo adingekayo ekujikeni ahlinzekwa ukungqubuzana okumile phakathi kwamasondo nendawo yomgwaqo. Uma isivinini siphezulu kakhulu uma ujika, amandla aphakathi nendawo F adingekayo makhulu kunokungqubuzana okumile okuphezulu, futhi imoto izokwenza ukunyakaza okumaphakathi futhi ibangele izingozi zomgwaqo. Ngakho-ke, izimoto azivunyelwe ukweqa isivinini esishiwo emajikeni omgwaqo. Amasondo okugaya agijima ngesivinini esiphezulu, ama-flywheels, njll. avame ukuphuka futhi adubule ngesivinini esikhulu ngenxa yamandla ezinto ezibonakalayo nokuqhekeka kwangaphakathi.

Yini i-centrifugal force?
I-Centrifugal force ingamandla abonakalayo, ukubonakaliswa kwe-inertia, esusa into ezungezayo kude nendawo yayo yokuzungeza. Ku-Newtonian mechanics, amandla amaphakathi asetshenziselwe ukuveza imiqondo emibili ehlukene: amandla angasebenzi abonwa kufreyimu yereferensi engeyona inertial, kanye nebhalansi yamandla amaphakathi. Kumakhenikha e-Lagrangian, amandla amaphakathi kwesinye isikhathi asetshenziswa ukuchaza amandla ajwayelekile ngaphansi kwesistimu yokuhlanganisa ejwayelekile.
Esimeni esijwayelekile, amandla e-centrifugal akuwona amandla angempela. Umsebenzi wayo uwukuqinisekisa kuphela ukuthi imithetho yokunyakaza ye-Newton isengasetshenziswa kuhlaka oluzungezayo lwereferensi. Awekho amandla we-centrifugal kuhlaka lwereferensi ye-inertial, futhi amandla angasebenzi adingeka kuphela kuhlaka lwereferensi olungeyona inertial.
Cabanga ngediski ezungeza isikhungo sayo ngesivinini esingu-ω. Ku-disk kukhona ibhulokhi yokhuni ye-mass m, exhunywe ngentambo, enye ingxenye yayo igxilwe enkabeni yediski (futhi isikhungo sokujikeleza). Ubude bentambo ngu-r. Ibhulokhi yokhuni izungeza nediski. Ngokucabanga ukuthi akukho ukungqubuzana, ibhulokhi yokhuni iyajikeleza ngenxa yokushuba kwentambo. Kumuntu obukayo ozungeza idiski, ibhulokhi yokhuni imile. Ngokomthetho ka-Newton, amandla anetha kubhlokhi yokhuni kufanele abe uziro. Kodwa-ke, ibhulokhi yokhuni ingaphansi kwamandla owodwa kuphela, ukushuba kwentambo, ngakho-ke amandla anetha akusiwo uziro. Ingabe lokhu kwephula umthetho kaNewton? Umthetho ka-Newton usebenza kuphela ohlelweni lwe-inertial, kodwa isistimu yereferensi yesibukeli esizungeza idiski iyisistimu engeyona inertial, ngakho-ke umthetho kaNewton awubambeli lapha. Ukuze umthetho ka-Newton usabambe ohlelweni lwe-non-inertial, i-inertial force, okuyi-centrifugal force, idinga ukucashunwa.
Ubukhulu bamandla we-centrifugal bulingana nokucindezeleka okuhlinzekwa yintambo, kodwa isiqondiso siphambene. Ngemva kokwethulwa kwamandla we-centrifugal, ngokombono womuntu obukayo ozungeza idiski, ibhulokhi yokhuni ifakwa ngesikhathi esifanayo ngaphansi kokungezwani kwentambo namandla e-centrifugal, alingana ngobukhulu futhi aphikisana nendawo, futhi amandla anetha ayiziro. Ngalesi sikhathi, ibhulokhi yokhuni imile, futhi umthetho kaNewton uqinisile.
