Kusankha pa mavuto mphamvu. Mfundo D'Alembert a

Monga sayansi osiyana okonzera ongolankhula chiphunzitso chimene chimagwirizanitsa malamulo onse a zoyenda makina ndipo mogwirizana kwa matupi zakuthupi. Chitukuko cha sayansi pachiyambi monga gawo sayansi, kutenga monga maziko axiomatic, izo likupezeka mbali yapadera ya sayansi.

Yothetsera mavuto a mphamvu mu chimango okonzera ongolankhula mutu ndi wosalira kwambiri ntchito d'Alembert mfundo. Iwo kwagona kuti kugwirizanitsa wa mphamvu zonse za yogwira, amene kanthu pa mfundo za dongosolo mawotchi, ndi zochita kumangidwa alipo chifukwa amaganizira otchedwa mphamvu inertia. Mwamasamu, izi chimaonetsera chimangirizo za zinthu zonse zimene tanena, zimene zimabweretsa ndi ziro.

Sam D'Alembert Leron Jean (1717-1783) amadziwika dziko monga mphunzitsi wamkulu, amene lakwaniritsa zikayenda bwino kwambiri zosiyanasiyana za sayansi. Masamu, zimango, nzeru anakumana kusanthula maganizo ake kufunsira. Chifukwa cha ntchito za D'Alembert nakhudza machitidwe chuma (mfundo D'Alembert a), ponena masiyanidwe maikwezhoni awo, womwe kukafola mwa malamulo. Jean Leron analungamitsidwa perturbation chiphunzitso cha mapulaneti, Yoswa chidwi kuphunzira ndi chiphunzitso cha mndandanda ndi masiyanidwe maikwezhoni, kusanthula masamu. A fuko French, D'Alembert anakhala aulemu yachilendo membala wa St. Petersburg Academy of Sciences.

Mtengo katswiri wa ku France, amene anayambitsa mfundo za kuthetsa mavuto zovuta za mphamvu, amenenso limadziwika ndi dzina lake, kwagona kuti, chifukwa cha ntchito zake zochita zako zazikulu amaloledwa kugwiritsa ntchito njira zophweka kwambiri okonzera zowerengera. Chifukwa kuphweka ndi kupezeka kwa ichi mfundo (mfundo D'Alembert) wapeza ntchito lonse okonza ntchito.

Ife tigwiritse ntchito mfundo ya d'Alembert kwa mfundo zakuthupi

Kukhazikitsa njira yunifolomu, imaphunzira aligorivimu a dongosolo limodzi makina amathandiza mfundo D'Alembert. Pankhaniyi palibe kudalira zinthu aliyense oletsa kayendedwe ake. Mphamvu masiyanidwe maikwezhoni za kayendedwe ndi mawonekedwe a maikwezhoni mgwirizano. Mwachitsanzo, kutenga kufufuza nonfree zina zakuthupi mfundo M amene zikugwira gulu limodzi pamapindikira AB mu chifukwa cha zochita za mphamvu yogwira ndi chotsatira F, ingagwiritsidwe ntchito kalembedwe N kwa mphamvu anachita (amadza pamapindikira AB pa M). Dziwitsani gulu F, N, O mu aone kuti pali zofunika kufotokoza mphamvu ya mfundo timapeza dongosolo convergent kuti akufotokoza mgwirizano chikhalidwe cha dongosolo imeneyo. Mtengo wa F limafotokoza kanthu za mphamvu inertia ndipo ali ndi phindu negative. Izi ndi ntchito d'Alembert mfundo mu anapezazo ndi kulemekeza mfundo zakuthupi.

Tikumbukenso kuti ndi njira imeneyi ife kutenga ndithu makonzedwe aone kuti pali magulu kogwirizana, ntchito moyenera mphamvu za inertia a dongosolo. Koma ngakhale izi, d'Alembert mfundo imapereka yabwino ndi njira yothandiza mavuto a mphamvu.

Kugwiritsa ntchito D'Alembert mfundo dongosolo mawotchi

Popeza akwanitsa kuchita zabwino mu mphamvu ya vuto mfundo chuma, tikhoza kukachita Baibulo zovuta zambiri vuto lomwe lili ndi mfundo d'Alembert kwa dongosolo mawotchi.

The aone kuti pali chifukwa dongosolo si wosiyana kwambiri kuchokera aone kuti pali chifukwa mfundoyo. Kusiyana kofunika kwagona kuti aziwerenga dongosolo makina adamuwumiriza nthawi iliyonse ikukhudza kupeza chotsatira a magulu onse ndalama mosiyanasiyana ndi ubwenzi wa makamu mfundo inertia.

Pogwiritsa ntchito njira pamwamba ndi mfundo sanamuthawe kumatsutsana lamulo lofunika a sayansi. M'malo mwake, ngakhale chiwerengero ena a poached kuti magawowa posankha zochita. Njira sizinayambe balamanthu, mfundo yaikulu zonse zochokera zikuluzikulu malamulo a Newton, mfundo German-Euler kuti muli chitukuko mu mfundo za d'Alembert.
