Le nhlangano yenkolo yokulwela rotary njengendlela yokuthola ezihambayo emkhathini

Ake ucabange - flying Saucers, kungaba enzeka yangempela ngokuya ucwaningo zezemfundo, kungakhathaliseki kukhona incazelo ezwakalayo lesi simanga? Ekuqaleni, masikhumbule ukuthi sesivele laziwe kubo bonke. isayensi Academic is neshaya iqiniso ukuthi noma yikuphi ukunyakaza kumelwe kwandulelwe umuzwa wokwenyanya. Uma kungenjalo, lokhu Eqinisweni ubizwa nangokuthi "inkomba" ukunyakaza, lapho ayethé chithi saka emzimbeni ezihambayo, okuhlanganisa nokuba ukunyakaza rotary, is wacasulwa nezinye mass.

In izinhlelo avaliwe isamba sazo zonke amabutho angaphandle, uhlala njalo okufanayo. Uma sikubeka kalula, maphakathi noma iyiphi inhlangano okwenzeka emhlabeni futhi ngaphakathi wo orbit ucwaningo ngokwayo seredinka wonke. Lo mthetho ubhekelela zonke izinto futhi zonke izimoto ezaziwa emhlabeni namuhla.

imithetho eyisisekelo, esekelwe lapho bonke mass zokuxhumana esikhaleni avaliwe, okuyinto Umhlaba, ukukhonza ezintathu umthetho Newton, ezibizwa umthetho ukulondolozwa amandla, umthetho futhi umthetho pulses we umfutho emincane. Uma incazelo enembile wale mithetho ayikwazi baphetha ngokuthi maphakathi mass isikhala avaliwe lapho ukunyakaza ukujikeleza alushintshi.

Zikhona okunye energy kinetic ka ezinyakazayo ukujikeleza, okuyinto awusekelwe isenzo amabutho angaphandle, ukuthi akuyona "ukwesekwa"? Ebhekisela isibonelo.

Ake sithi ube isilinda bezungeza isilinda ngesikhathi sphere ezivamile, namandla kakhulu futhi isisindo ukuphotha ibhola elincane. Uma udala shock wave elincane ngemuva ibhola (ukuqhuma), ngokomthetho yesibili Newton, isivinini ushintsho ibhola ujikeleza Kuyothi ngokulingana umphumela kuso kwamandla (isb amandla ukuqhuma), kanye ukunyakaza kufanele ziqondiswe ngakujantshi baqonda ngqo lapho ibutho alufakwa kwaba enamathiselwe.

Kwenzekani kulesi, isibonelo esikhethekile? Eyesibili umthetho Newton akusho phakathi isiqondiso Translational noma ngokushintshana. Ngenxa yalokho, le nhlangano ukujikeleza futhi Translational ka uMbhalo kufanele kubhekwe amandla alinganayo isetshenziswa uMbhalo. It kuvela ukuthi ehamba izungeze ezinye umzimba yombambiqhaza kungenzeka ubheke le umzimba phambili futhi ngokunyakaza yomugqa, isiqondiso lapho kuvumelana isiqondiso amandla osetshenziswayo.

Kusho iqonde futhi leso sicelo Translational bento eyodwa kungadala amandla oveza ngezibulo ezinyakazayo ukujikeleza lomunye into. Lolu dengezi, kulesi sibonelo, inobungako ezinkulu, isihlobo ukuba ibhola. Uma lokhu akunjalo, ukuhamba eksisi eyinhloko isilinda kungaba njengokugxeka ukunyakaza rotary ibhola. Nokho, ukuhlola Ngokwesibonelo yethu, singakwazi ukucabanga ukuthi unesikhathi ilungelo khona, inertia ezinjalo, okukhona kuyo amandla isetshenziswa maphakathi uMbhalo kuzolenza iqonde phambili ezinyakazayo.

Ngakho, leso sicelo ukujikeleza bento eyodwa kungabangela ngokunyakaza rectilinear futhi reciprocating komunye, futhi womathathu umthetho Newton is umthetho.

Isayensi yanamuhla sesivele sifike esimweni ukuthi uyakwazi ukudala i "engasekelwe" injini olusebenzisa okuqhubekayo, avaliwe iluphu inqubo namandla isizukulwane ozosungula ngokunyakaza yokunyathelisa. Le ndlela ukunyakaza ingasetshenziswa kunoma iyiphi imoto, ngebhayisekili, kanti abafinyelela enkulungwaneni esosweni ezindizayo, futhi izindleko-ukusebenza kwale nqubo uyoba lutho wafana.
