Ithonya imigqa (Mechanics kwesakhiwo) incazelo and definition

Kanjani ukwakha umugqa ithonya? Mechanics Bezakhiwe kusekelwe kinematic Lagrange indlela. essence yayo itholakala iqiniso ukuthi kulesi simiso isebujameni ephelele yakhoibrium, nomphumela we bonke khandlu displacement encane zero.

I ngokucacile indlela

Ukwakha umugqa ithonya ukusabela, umzuzwana eguqa, phuca iyimbangela ingxenye inikezwe ugongolo, wasebenzisa thize yezenzo. Ukuze uqale, susa isixhumanisi. Ngaphezu kwalokho, Imigqa ehlanzekile ithonya imizamo yangaphakathi ukuba libhekele umzamo odingekayo. Ngenxa manipulations ezinjalo uhlelo indlela kokuba degree elilodwa inkululeko. Ohlangothini lapho ukucindezeleka yangaphakathi uthathwa iqondiswa ukunyakaza okuncane. isiqondiso salo kufanele sibe afana amandla angaphakathi, kuphela kulesi simo kuyoba umsebenzi omuhle.

izibonelo ezakhiwe

Ngesisekelo ukunyakaza eqoshiwe yakhoibrium kwesibalo ngesinqumo ibalwa ithonya line yayo, ichaze force edingekayo.

Cabanga ngesibonelo sika-lezi izibalo. Yakha imigqa transverse amandla amathonya kwezinye A. kwesigaba Ukuze sibhekane nale umsebenzi, kubalulekile ukwakha elinikeziwe ukufuduka epure imishayo kusuka ukunyakaza olulodwa bebheke kwezitshalo amandla.

Ifomula sokunquma umzamo

Ukwakhiwa kolayini ithonya Kwenziwa usebenzisa ifomula ethize. It ubopha amandla oyifunayo, ubukhulu webutho okuyinto ethatha ugongolo, indawo sibalo ezakhiwe umugqa futhi eksisi yethonya umdwebo ngaphansi komthwalo. Futhi nge inkomba yokuthi okwamanje eguqa futhi tangent ulayini umthelela amabutho kanye eksisi hlangothi.

Uma isiqondiso ukusatshalaliswa umthwalo futhi amandla kanzulu uqondane isiqondiso mobile iyunithi amandla, babe value omuhle.

Okwamanje eguqa kuyasiza omuhle esimweni lapho kuvumelana isiqondiso ngokwewashi. Tangent uhilela izenzo ngesikhathi engela ukuzungeza esingaphansi engela kwesokudla. Lapho efeza izibalo ukusetshenziswa ne izimpawu zabo ahlelembise value futhi endaweni ithonya umugqa. Mechanics Bezakhiwe kusekelwe indlela kwezibalo kutsi bakwati kutakhela imidvwebo.

ichaze

Lapha izincazelo eziyisisekelo ezidingekayo ukwenza imidwebo qualitative izibalo. Ithonya umugqa - umugqa ohlanganisa amandla yangaphakathi kanye displacement a amabutho mobile olulodwa.

I lasetjentiswe ukukhombisa ushintsho ihlaziye amabutho yangaphakathi avela ngesikhathi iphuzu othize ugongolo ngenkathi ezihambayo kanye ubude ibutho olulodwa. Zibonisa ukwehlukahlukana e amaphuzu ezahlukene kubhekwe umzamo yangaphakathi enikeziwe ukusetshenziswa i umthwalo zangaphandle isilungisiwe. Ngokwezibalo ukwakhiwa okufana esekelwe irekhodi ibhalansi zibalo.

Amabili ezahlukeneyo kokwakhiwa

Ukwakhiwa ithonya imigqa in the ngemishayo okwamanje eguqa kungenzeka ezimweni ezimbili. Force ingabekwa ngakwesokudla noma ngakwesobunxele mayelana esetshenziswa sigaba. Uma ushiye indawo zamabutho ingxenye ku izibalo ngokukhetha amabutho ukuthi uyosithatha isinyathelo ngaso kanye. Ngakwesokudla yayo yesenzo kubhekwa kwesokunxele-wing amabutho.

multi-span uvumelanise

I amabhuloho, isibonelo, imishayo asizayo asetshenziselwa yokudlulisela i umthwalo zangaphandle engxenyeni Ukuthela lonke isakhiwo isakhiwo. Ugongolo eyinhloko ibizwa ngokuthi nguye base yenethiwekhi. Cabanga imishayo kwesiphambano, leso zitholakala ku-engela main kwesokudla.

Asizayo (owodwa span) ugongolo ibizwa ngokuthi, lapho unamathele umthwalo zangaphandle. kukho ezinjalo Ukudlulisa main ugongolo umthwalo kubhekwe engeyokuqala. Iphaneli endaweni etholakala phakathi zindawo ezimbili eliseduze. Futhi zivezwa amaphuzu-eksisi eyinhloko, okuyinto uvumelane imishayo esiphambanweni.

Izici

Uyini umugqa ithonya? Inchazelo kweThemu le e ugongolo elihlobene ne igrafu elibonisa ushintsho zezici ihlaziye lapho ezihambayo iyunithi amandla ugongolo. It ingaba njengesihluthulelo amandla phuca, eguqa isikhashana, ukusekela ukuphendula. Noma yimuphi imigqa ahlelembise ithonya ikhombisa ubukhulu izici ihlaziye ku yingasiphi isikhathi uma amandla okukuwo. Kanjani ukwakha imigqa ithonya semishayo? Kususelwa indlela kwezibalo ukulungiswa zibalo kwezibalo. Ngokwesibonelo, i-ugodo elula ngesikhathi eziveza ezimbili zungeza, elinesimo amandla esishukumisela ugongolo. Uma sikhetha ibanga elithile ngesikhathi esebenza kuwo, kungenzeka ukwakha umugqa ithonya ukusabela, ukwenza izikhathi kwesibalo ukwakha ezimbili iphuzu igrafu.

Khona-ke, i-ijika bebutho lateral yomthelela, le njongo, emigqeni ahlelembise ithonya esigabeni.

indlela cinematic ukuze

Kungenziwa esekelwe ukunyakaza komugqa ithonya yakhiwe. Izibonelo iziza enjalo zingatholakala ezimweni lapho ugodo ukuboniswa ngaphandle kokusekelwa ukuthi indlela Ungahambisa ohlangothini omuhle.

Ukwakha umugqa ithonya elithile ukugoba isikhashana kufanele linamathele kwesigaba lomnyango ekhona. Kulokhu, lo mshini okuholela ijikeleziswa ngumuntu engela mayunithi ku isiqondiso esihle.

Umuda ku transverse umthelela force kungenzeka ngesikhathi esincane esigabeni slide kanye ukunwetshwa ugongolo ngomunye ohlangothini omuhle.

Ungasebenzisa indlela cinematic ukwakha umugqa yokugoba isikhashana bese phuca amandla e ugongolo cantilever. Uma kucatshangelwa lwesokunxele baxhashazwe e ukunyakaza efana ugongolo kubhekwa kuphela ohlangothini tesekudla omuhle. Ngenxa yethonya lezingane emigqeni ngokuvumelana ifomula, ungakwazi ukubala yimuphi umzamo.

Izibalo indlela cinematic

Esikhathini izibalo indlela kinematic usebenzisa ifomula ohlobene inani ukwesekwa izinduku, inani besandla, le kokuhlanganisayo, degree of nenkululeko umsebenzi. Lapho abambele amanani anikeziwe inani degrees enkululeko kuyoba ilingane no-zero, umsebenzi kungaba azimisele wezibalo. Uma lesi sibalo izokhombisa ukuthi akanalo igciwane, umsebenzi wezibalo kungenzeki, enenani omuhle lamadigri enkululeko wenziwa ukwakhiwa weJiyomethri.

Ukuze wenze kube lula ukwenza izibalo, ukuba umbono ocacile ngokuthi izici umsebenzi disk in a multiple-ugongolo isakhiwo Floor isikimu.

Ukuze lolu shintsho kuya ezisekelweni lomnyango-fixed zonke kokuhlanganisayo yasekuqaleni ayatholakala ugongolo.

izinhlobonhlobo imishayo

It kucatshangwa izinhlobo eziningana multi-span imishayo. I ngokucacile uhlobo lokuqala wukuthi wonke besandla, ngaphandle, wasebenzisa lomnyango-ezithathekayo izisekelo kuqala. Uma esikhundleni ukusebenzisa ukwesekwa kokuhlanganisayo, uzobe kwakhiwa ugongolo olulodwa, lapho ngamunye ngeke bathembele console eduze ukuma.

Ukuze uhlobo lwesibili libhekene interlace besandla, okuyinto babe izisekelo ezimbili pivotally-ezithathekayo, span ngaphandle izisekelo. Kulokhu, indaba ngomhlangano wesifunda ngo-central console imishayo esekelwe imishayo unamathisele.

Ngaphezu kwalokho, izingodo zophahla enjalo, okuyinto ahambelana e izinhlobo ezimbili eyedlule. Ukuqinisekisa kwezibalo Definability ngemishayo ifaka, baphathe uxhumano ovundlile phakathi ukusekelwa ngakwesokudla ugongolo eduze. Ground floor kwisikimu Condominium izothunyelwa ugongolo eyinhloko kanye izingodo yesibili ezisetshenziswa izitezi.

Imidwebo yangaphakathi amandla izici

Ukusebenzisa isigaba imidvwebo ongenza ukwakhiwa idayagramu for ugodo olulodwa kusukela phansi engenhla kanye aphansi isiphetho kwaqanjwa. Ngemva Isakhiwo esesiphelile izifiso zezici zangaphakathi for phansi engenhla, kubalulekile ukuba ushintshe yonke amagugu ezitholakele ze- ukusabela kusekela ku kolunye uhlangothi bebutho, bese unamathisele nabo Isikimu phansi ngayinye sakhiwo. Esikhathini kwalo ukwakhiwa kukhona imidwebo predetermined umthwalo amabutho.

Ngemva kokuphothulwa ukwakhiwa kwamandla imidvwebo izici yangaphakathi eyenziwa isheke kwezibalo ephelele girder multispan. Lapho ehlola isimo kumelwe eneliseke, owawuthi isamba sazo zonke izenzo isekela amabutho enikeziwe zero. Kubalulekile futhi ukuba sihlaziye ukuhambisana umehluko dependences Izingxenye ngazinye ugongolo esetshenziswa.

Esikhathini igrafu, azwakalisa lo ukushintshashintsha ukwesekwa yangaphakathi noma isici amandla yokusabela ethile (predetermined) ingxenye isakhiwo, umsebenzi indawo umphumela wezimpahla ezinyakaza ngokuthi umugqa. Zisetshenziswa ukwakha kwesibalo kwezibalo.

Ukuze ubone ukuthi yangaphakathi amandla isici ukubala ukusabela isekela kolayini ezithile ithonya usebenzisa izethulo sokuqhafaza.

Computing Meaning

Ngomqondo obanzi Mechanics kwesakhiwo uthathwa njengoba isayensi okhuluma ekuthuthukiseni izindlela sibalo futhi ukuqinisekiswa izakhiwo nezimiso nezakhiwo ukuzinza, amandla nokuqina. Siyabonga ikhwalithi kanye nesikhathi izinkokhelo ekuqineni kungaqinisekisa ukuphepha ekwakhiweni kwezakhiwo, ukumelana yabo Imininingwane amabutho zangaphakathi nezangaphandle.

Ukuze kuzuzwe elamukelekile isebenzisa inhlanganisela umnotho futhi ihlala isikhathi eside.

Izibalo ukuqina litfuba izinkomba esibucayi amathonya zangaphandle ukuqinisekisa ukuphepha ibhalansi unikezwa ukuma nesikhundla esimweni sikhubazekile.

Izibalo ukuqina yilezi ukukhomba ezahlukene zamagciwane ezahlukeneyo (kwenze deflections, kunyakaza) ngenxa operation egcwele okuyinto ayifakiwe izakhiwo, kuphakama amandla kwesakhiwo usongo.

Ukuze ugweme yimuphi izingozi, kubalulekile ukuba afeze izibalo ezinjengalezi, ahlaziye izinkomba ezifanele etholakala umkhawulo amagugu.

Okwamanje, ukwakhiwa umakhenikha isebenzisa okunhlobonhlobo izindlela eziqinile izibalo okuye ukuhlolwa ukwakhiwa kanye ne-engineering umkhuba ezinemininingwane.

Banikezwe sesimanje okuqhubekayo kanye nokuthuthukiswa embonini yezokwakha, kuhlanganise isisekelo yayo theory, singaxoxa mayelana nokusetshenziswa omusha ngezindlela izinga onokwethenjelwa futhi okusezingeni eliphezulu ukwakha imidwebo.

Ngomqondo emincane Mechanics kwesakhiwo elihlobene ne-izibalo theory ezindukwini ezimbili, emapheshana, akha isakhiwo. Njengoba base Mechanics ezihlelekile ayisisekelo physics, mathematics, izifundo zokuhlola.

Inkokhelo izikimu, ezisetshenziswa Mechanics kwesakhiwo ngoba amatshe, ukhonkolo, izinkuni, izakhiwo zensimbi, ngeke kugwenywe ukungaqondi kahle lapho kwakhiwa izakhiwo kanye nezinhlaka. Kuphela ilungelo imidwebo pre-wakha kungenzeka ukukhuluma mayelana nokuphepha kanye ukuthembeka izakhiwo wadala. Ukwakhiwa ithonya imigqa e imishayo kuyingozi ngempela futhi isenzo wemfanelo, ngoba ukunemba isenzo incike ezimpilweni zabantu.
