Ukusheshisa kwe-radial - izinkinga nezixazululo

Ukusheshisa imisebe - izinkinga nezixazululo

1. Yiliphi igrafu elingezansi elibonisa ubudlelwano phakathi kokusheshisa kwe-centripetal noma ukusheshisa kwe-radial (a _R ) kanye nejubane eliqondile (v) ekuhambeni okujikelezayo okufanayo.

Ukusheshisa ngemisebe - izinkinga nezixazululo 1

Isixazululo:

Isibalo sokusheshisa kwe-radial:

a _R = ukusheshisa kwe-radial , v = ijubane eliqondile , r = ibanga ukusuka ku-axis yokujikeleza.

Sihlola ubudlelwano phakathi kokusheshisa kwe-radial (a _R ) nejubane eliqondile (v) ukuze ibanga elivela ku-axis yokujikeleza (r) lihlale linjalo. Isibonelo, r = 1.

2. Ibhola lijikeleza esitsheni esinobubanzi obuyimitha eli-1. Uma ijubane le-angular lingu-50 rpm, liyini ijubane eliqondile kanye nokusheshisa kwe-radial kwebhola?

Kwaziwa:

Ububanzi besiyingi (D) = 1 m

Irediyasi yesiyingi (r) = 0,5 m

Isivinini se-angular (ω) = 50 rpm = 50 revolutions / 1 minute

1 uguquko = 2π radian

Ukujikeleza okungu-50 = 50 (ama-radian angu-2π) = ama-radian angu-100π

Umzuzu owodwa = imizuzwana engama-60

Ijubane le-angular (ω) = ama-radians angu-100π / imizuzwana engu-60 = (10π/6) ama-radians/isekhondi

Okufunwayo: Isivinini esiqondile (v) kanye nokusheshisa kwe-radial (a _R )

Isixazululo:

Isivinini esiqondile (v):

v = r ω = (0.5)(10π/6) = 5π/6 m/s

Ukusheshisa kwe-radial (a _R ):

a _R = v ² /r = (5π/6) ² : 0.5 = 25π ² /36 : 0.5 = (25π ² /36)(1/0.5)

a _R = (25π ² /18) m/s ²

3. Into ihamba ngesivinini esingaguquki u-v embuthanweni onerediyasi ka-R kanye nokusheshisa kwe-radial u- _R . Uma ukusheshisa kwe-radial kuba izikhathi ezimbili, khona-ke u-v uba izikhathi ezingu-……. kanye nerediyasi iba izikhathi ezingu-…….

Bhekafuthi Amasekethe e-DC alula - izinkinga nezixazululo

Isixazululo:

Isibalo sokusheshisa kwe-radial:

Uma ukusheshisa kwe-radial (a _R ) = 1 khona-ke ijubane eliqondile (v) = 1 kanye ne-radius (r) = 1:

Uma ukusheshisa kwe-radial (a _R ) = 2 khona-ke ijubane eliqondile (v) = 2 kanye ne-radius (r) = 2:

Uma ukusheshisa kwe-radial kuba izikhathi ezimbili, khona-ke ijubane eliqondile (v) liba izikhathi ezimbili kanti i-radius yendilinga iba izikhathi ezimbili.

Q: Kuyini ukusheshisa kwe-radial futhi kuhlobene kanjani nokunyakaza okujikelezayo? A: Ukusheshisa ngemisebe izinga lokushintsha kwejubane le-tangential ekuhambeni okujikelezayo. Kuhlala kuqondiswe enkabeni yendilinga, futhi ubukhulu bayo bunikezwa yi $a_{r} = v ^{2}$ ,/r kuphi $v$ yijubane le-tangential, futhi $r$ iyindawo engaba yindilinga.
Q: Kungani ukusheshisa kwe-radial kubizwa nangokuthi ukusheshisa kwe-centripetal? A: Ukusheshisa ngemisebe kubizwa ngokuthi ukusheshisa nge-centripetal ngoba igama elithi “centripetal” lisho “ukufuna indawo ephakathi.” Lokhu kusheshisa kuqondiswe enkabeni yendlela eyindilinga, okuchaza uhlobo lwamandla adingekayo ukugcina into ihamba kuleyo ndlela.
Q: Ukusheshisa kwe-radial kushintsha kanjani uma i-radius yendilinga iphindwe kabili kuyilapho ijubane lihlala lingaguquki? A: Uma i-radius iphindwe kabili futhi ijubane lihlala lingaguquki, ukusheshisa kwe-radial kuzoncishiswa ngesigamu, njengoba kuhambisana ngokuphambene ne-radius.
Q: Ingabe ukusheshisa kwe-radial kungenzeka ngokunyakaza okuqondile? Kungani noma kungani kungenjalo? A: Cha, ukusheshisa kwe-radial kubhekisela ngqo ekusheshiseni ngokunyakaza okujikelezayo. Akusebenzi ekunyakazeni komugqa oqondile ngoba akukho ukushintsha okuqhubekayo endleleni eya endaweni ephakathi eqondile.
Q: Uma into iphumule endleleni eyindilinga, kuyoba yini ukusheshisa kwayo okuqondile? A: Uma into iphumule, ijubane layo eliqondile liyi-zero, futhi ngenxa yalokho, ukusheshisa kwayo okuqondile nakho kuzoba yi-zero.
Q: Ukusheshisa kwe-radial (centripetal) kuhlobene kanjani namandla e-centrifugal? A: Ukusheshisa kwe-centripetal kuwukusheshisa kwangempela okuya enkabeni yendlela eyindilinga, kanti amandla e-centrifugal angamandla aqanjiwe abonakala esebenza ngaphandle uma ebhekwa ngohlaka lokubhekisela olujikelezayo. Ayalingana ngobukhulu kodwa aphambene ngendlela.
Q: Kwenzekani ekusheshiseni kwe-radial uma ijubane lento ehamba endleleni eyindilinga liphindwe kabili? A: Uma ijubane liphindwe kabili, ukusheshisa kwe-radial kuzophindwa kane. Ukusheshisa kwe-radial kuhambisana nesikwele sejubane, ngakho-ke ukuphindwa kabili kwejubane kwandisa ukusheshisa ngesilinganiso sesine.
U: Iyiphi indima edlalwa ukungqubuzana ekuhlinzekeni ukusheshisa kwe-radial emotweni ejikayo? A: Ukungqubuzana phakathi kwamathayi nomgwaqo kunikeza amandla aphakathi nendawo adingekayo ukuze kusheshiswe imisebe. Ngaphandle kokungqubuzana okwanele, imoto ngeke ikwazi ukushintsha indlela nokugcina indlela eyindilinga, futhi esikhundleni salokho izoqhubeka iqonde.
Q: Kungenzeka yini ukuthi ukusheshisa kwe-radial kube kubi? Kungani noma kungani kungenjalo? A: Ukusheshisa ngemisebe kuhlale kuqondiswe enkabeni yendilinga, ngakho-ke kuchazwa njengokuhle kuleyo ndlela. Akunakuba kubi ngoba indlela yokusheshisa ngemisebe ngokwencazelo iqondiswe enkabeni yendilinga.
U: Amandla adonsela phansi afaka kanjani isandla ekusheshiseni kwe-radial endabeni yezinto zasezulwini ezifana namaplanethi azungeza ilanga? A: Endabeni yamaplanethi azungeza ilanga, amandla adonsela phansi phakathi kwalezi zidumbu ezimbili asebenza njengamandla aphakathi nendawo, ahlinzeka ngokusheshiswa kwe-radial okudingekayo ukugcina iplanethi isemjikelezweni wayo oyindilinga (noma cishe ojikelezayo). Amandla adonsela phansi agcina iplanethi ihamba endleleni ezungeze ilanga, kunokuba ihambe ngendlela eqondile.
