Modulus Young kunye ingqiqo yayo ephambili emzimbeni

Le modulus of luthambe longitudinal ye nesixhobo yokwakha, okanye modulus Young kaThixo, ebizwa ngokuba ubuninzi emzimbeni leyo olwahlula yipropathi eziphathekayo, ngokubonelela ngokomelela kwabo deformation, ukwenza kwicala longitudinal.

I parameter ephawula yobulukhuni izinto eziphathekayo.

igama lomnqongo ingqamana igama uThomas Young - yamachiza odumileyo British-nzulu oye wafunda iinkqubo ucinezelo kunye nokwandiswa eqinile. Oku kuboniswa ixabiso ebonakalayo lencwadi Latin modulus E. Young ulinganiswa Pascals.

modulus Ipharamitha Young okanye modulus of luthambe longitudinal lisetyenziswa izibalo ezahlukeneyo ngexesha izixhobo uvavanyo phezu isidanga deformation, compressive eqine kunye flexural.

Ndimele ndithi ukuba uninzi izinto zokwakha ezisetyenziswa nani bokuhlala modulus Young elikhulu ngokwaneleyo, nto leyo ngokuqhelekileyo zomyalelo Septemba ¹⁰ Pa na. Ngoko ke, "Giga" (uTsvangirai) asebenzise Ufakelelo ezininzi lula yokubala nokurekhoda.

Ezi zilandelayo izalathi si zokunikwa modulus Young ngenxa kwezinye izinto zokwakha, ezisetyenziswa rhoqo ukwenzela iinjongo ezahlukeneyo ezisebenzayo. Kuba phezu amandla iimpawu zazo zixhomekeke ayasiqinisekisa izakhiwo yokwakha kunye nezinye izinto.

Ngokutsho etafileni, izinga iphezulu umnqongo bobabo intsimbi, kwaye ubuncinane - emthini.

ukuzimisela olubonakalayo lwe modulus Young kukuba kunokwenzeka usebenzisa uxinzelelo umzobo eyodwa ebonisa kwigophe elifunyenwe omnye enye ekufanisweni uqinile kwiimvavanyo ngokuphindaphindiweyo.

Kulo mzekelo, intsingiselo ebonakalayo modulus i Young kukuba ukufumana ubudlelwane yemathematika uxinezeleko eqhelekileyo ohambelana parameters abahluza inxalenye ethile yetshathi ethile kwangaphambili mda umlinganiselo σ _mi.

Xa iimbalo ibinzana modulus Young njengoko lulandelayo: E = σ / ε = tgα

Kufuneka kwakhona wathi modulus i Young kutshata naye eyongeziweyo ukulingana kwinkcazo zemathematika yomthetho Hooke kaThixo, yona na ngolu hlobo lulandelayo: σ = Eε

Ngoko ke, lo udibaniso ngqo luthambe modulus iimpawu longitudinal kulinganiswa woku-amacandelo izinto inxaxheba kuvavanyo ngumkhinkqi, wavakalisa usebenzisa iparameters ezifana EA kunye E1.
EA - elithile ngumkhinkqi eqine, izinto compressive yayo cross-candelo, apho A - ixabiso yentonga cross-yecandelo ndawo.

E1 - ngumlinganiselo le ngqongqo flexural umbandela kwicandelo layo emnqamlezweni, apho 1 - ixabiso yezihlunu mzuzu inertia, leyo kuvela izinto ipytyvaemogo yecandelo.

Ngenxa yoko, modulus i Young - luphawu bonke, nto leyo yenza amaqela ezininzi elichaza iimpawu noshowo mbandela.
