Mphamvu coriolis

Pa maonekedwe-zabodza sayansi ndi pafupipafupi chodabwitsa azinyadira kutsutsana kwambiri kuti kodi mphamvu Coriolis, ndi zomwe ziri mawonekedwe ake kuonekera. Ngakhale atulukira ake lolemekezeka zaka - chodabwitsa wakhala mwamsanga anafotokoza monga 1833 - anthu ena ndi zina wosokonezeka mu mosiyana. Mwachitsanzo, chifukwa chakuti ambiri mwa mphamvu Coriolis kugwirizana ndi zochitika nyanja ndi mlengalenga, pa intaneti mungapeze mfundo imene angatifooketsere la mitsinje ya kumpoto kwa dziko lapansi amapezeka kumanja, ndi cha Kumwera kanthu otsukira ndikupha tizilombo madzi ambiri pa gombe kumanzere. Ena amanena kuti zodabwitsazi amalenga mphamvu Coriolis. owatsutsa kufotokoza china chirichonse: wa kasinthasintha olimba pamwamba dziko umalimbikitsa pang'ono msanga (zochepa inertia) kuposa kulemera kwa madzi komanso chifukwa cha kusiyana ndi M'MALO. Ngakhale zina zikuchitika mu nyanja, kwenikweni, "olakwa" wa mphamvu Coriolis. Kulephera kudziwa izo kuchokera osiyanasiyana zinthu zina. Coriolis mawonetseredwe monga mphamvu ya yokoka mogwirizana angathe.

Tiyeni amaonetsera mtundu wa mphamvu, ndipo n'chifukwa chiyani ngati chidwi. Popeza lathuli tinganene kuti sanali inertial system (kusuntha ndi atembenuza), ndiye ndondomeko iliyonse, ankaona poyerekezera izo, ayenera kuganizira inertia. Kawirikawiri ntchito kufotokoza imeneyi pendulum kutalika kuposa 50 mamita ndi kulemera kwa makumi makilogalamu. Komanso chidwi ndi n'kupuma atayima pansi pa ndege imene pendulum alili imazungulira circumferentially. Ngati mtengo wa liwiro rotational wa padziko lonse kukhala apamwamba kuposa nthawi oscillation wa pendulum ndi, ndege ake notional adzakhala osamukira ku mbali ya kumpoto kwa dziko lapansi, onsewo mu pandunji pa mbali maola patsogolo. Tikawonetsetsa kuwonjezeka nthawi ndi apamwamba kuposa chingandithandize lapansi mlingo kasinthasintha mu anasintha motsogozedwa mobwerera kuyenda. Izi zimachitika chifukwa chakuti kasinthasintha wa dziko mu dongosolo amalenga mathamangitsidwe rotational wa pendulum, ndi vekitala amene akugwiritsa ndege kugudubuzika.

Kufotokoza, mukhoza kugwiritsa ntchito chitsanzo cha moyo. Ndithudi, aliyense monga mwana atakwera carousel, amene ali onsewo ndi zina okhota mathamangidwe litayamba lalikulu. Taganizirani mfundo ziwiri pa chimbale, mmodzi pafupi olamulira chapakati (A) ndipo chachiwiri - m'mphepete pafupi utali wozungulira wa (B). Ngati munthu amene ali pa mfundo A akudzipereka kusamukira mfundo B, ndiye, pa Koyamba, kwambiri mulingo woyenera zoyenda njira ndi molunjika mzere A-B kwenikweni utali wozungulira litayamba. Koma ndi sitepe iliyonse munthu mfundo B ali ankatembenukira, monga chimbale cha sangathenso. Chifukwa, ngati ife apitiriza kulimbikitsa pamodzi munakonza mzere-utali wozungulira, pamene utali wozungulira mfundo B, silinalinso adzakhala chifukwa kukondera. Ngati anthu kusintha njira zawo mogwirizana ndi boma lenileni la B, ndiye njira yodutsamo udzaonetsera mzere yokhota kumapeto, mafunde, pamwamba umene ukuperekedwa malangizo a kasinthasintha. Komabe, pali njira kuchokera A kuti B mu mzere wolunjika: ndikofunikira kuonjezera liwiro kuyenda, kuwauza thupi (munthu) mathamangitsidwe. Ndi kuwonjezeka mtunda A-B kukhalabe kayendedwe rectilinear zofunika zonse kuwonjezeka umagunda mofulumira. kusiyana anafotokozedwa ndi mphamvu centrifugal mu malangizo a chikugwirizana masika ndi utali wozungulira pa circumference onsewo.

Choncho, chokwawa padziko chinthu onsewo ali ndi zotsatira za mphamvu Coriolis. Chilinganizo ndizoonekeratu:

F = 2 * ndime * mamita * cosFi,

kumene mamita - Unyinji wa thupi ikuyenda; ndime - liwiro gulu; cosFi - phindu limene amaganizira ngodya pakati pa malangizo kuyenda ndi olamulira wa kasinthasintha.

Kapena, mu chifaniziro vekitala:

F = - mamita * ndi,

kumene - mathamangitsidwe wa Coriolis. "-" chizindikiro ukapezeka chifukwa mphamvu m'thupi kusuntha zosiyana malangizo.
