Kaha coriolis

I runga i nga huinga tupurangi-pūtaiao ki te auautanga mīharo whakakā tautohetohe nui e pā ana ki te mea ko te kaha Coriolis, me aha e ona faaiteraa kitea. Ahakoa ona āhuatanga tau huihuinga - Kua tītohunga kua whakaahuatia rite wawe rite 1833 - he puputu'u ētahi wā i roto i te whakatau etahi iwi. Hei tauira, mai te nuinga o te ope Coriolis e pā ana ki te ari i roto i te moana, me te huru, i runga i te ipurangi ka taea e kitea e koe i te kerēme e te whakaititanga o te awa o te tuakoi raki puta i te taha ki matau, a ka i roto i te mahi paru tahinga Southern o te wai ko te nuinga i runga i te taha maui. Ētahi tautohe e hangaia e tenei āhuatanga i te ope Coriolis. Ratou hoariri whakamārama katoa atu: i te huringa o te mata totoka o te ao neke paku tere (iti iho tūpuku) atu i te taimaha o te wai, me te te mea o tenei rerekētanga ko te whakauru. Ahakoa etahi o nga tukanga tango wahi i roto i te moana, tino, "hara" o te ope Coriolis. Uaua i roto i te whakatau i reira i te whānuitanga o ētahi atu awe. faaiteraa Coriolis rite te kaha o tō pūmanawa pāhekoheko.

Kia tautuhi a he aha te ahua o te kaha, me te aha ko te moni taua. Mai taea te whakaaro to tatou paraneta te pūnaha kore-inertial (nekehanga me te tītaka), na kia tango i tetahi tukanga, tirohia i roto i te pā ana ki reira, ki te pūkete te tūpuku. Ko te tikanga e whakamahia ana mō te whakamārama i tēnei roa ngā tautau nui atu i 50 m me te taimaha o tekau o kirokaramu. Ano, he kaimātakitaki āhua tū, e tu ana i runga i te rererangi papa i roto i nei te hīrere tautau huri circumferentially. Ki te pai kia teitei ake i te uara o te tere hurihuri o te ao te wā o oscillation o te tautau, ka kia ngā ona rererangi notional i te aronga o te tuakoi raki, tītaka i te ritenga atu, i te taha ki te ahunga whakamua haora. Engari, te whakanui ake i te wā he tiketike ake ka hua auau hurihanga o te whenua i roto i te nekehanga i roto i te ahunga o te tākaraka haere. tupu tenei e tika ana ki te meka e hangaia e te huringa o te ao i roto i te pūnaha i te whakaterenga hurihuri o te tautau, he vector e te hünuku te manureva awhiowhio.

Hei whakamārama, ka taea e koe te whakamahi i te tauira o te ora. Pono, ia rite te tamaiti e noho ana i runga i te carousel, i te mea he hurihuri ki te tetahi tere koki kōpae nui. A feruri na e rua ngā i runga i te kōpae, tetahi e tata ana te tuaka pokapū (A) me te tuarua - i runga i te mata e tata ana ki te pūtoro (B). Ki te whakatau te tangata e he i pūwāhi A, ki te neke ki te wāhi B, ka, i mawhiti tuatahi, te tino tino pai ara nekehanga ko ko mau he aho tika A-B he pūtoro kōpae. Otiia ki ia taahiraa e neke te tangata ira B, kia rite ki te hurihuri i te kōpae. Ka rite ki te hua, ki te mau tonu tatou ki te neke haere i te rārangi-pūtoro whakaritea, e ka te pūtoro o te pūwāhi B, ko reira kore e kia tika ki te rītaha. Ki te mea ka whakarite iwi ratou ara i roto i runga i te āhua tūturu o B, na ka tapae te trajectory he aho kōpiko, he poipoi, te tihi o i whakahaua e ki te aronga o te hurihanga. Heoi, i reira he he ara ki te tiki atu i te ki te B i roto i te rārangi torotika: ko reira e tika ana ki te whakapiki ake i te tere o te kaupapa, korero te tinana (tangata) whakatere. Ki te whakanui ake i tawhiti A-B ki te mau tonu i te kaupapa torotika tika ki auau pini te whakanui ake katoa. whakaahuatia te rerekētanga e te kaha turai i roto i taua aronga o te hāngai muri ki te pūtoro i runga i te paenga tītaka.

Na, neke i runga i te ahanoa tītaka he pānga o te ope Coriolis. Ko te tātai whai reira:

F = 2 * v * m * cosFi,

te wahi m - papatipu o te tinana neke; v - tere o kaupapa; cosFi - uara i tango ki pūkete te koki i waenganui i te ahunga o te kaupapa, me te tuaka o te hurihanga.

Ranei, i roto i te vector kanohi:

F = - m * te,

i reira he - whakatere o Coriolis. "-" te panga o tohu no te mea te kaha i te tinana neke te aronga ritenga.
