Coriolis simba

On the ekunyebera yesayenzi forum pakuparadzwa maitikiro vesa chakakomba gakava pamusoro chii simba Coriolis, uye chii vari kuonekwa kuoneka. Pasinei kwayo seane uchenjeri zera zvakawanwa - Fani akarondedzerwa se mangwanani se 1833 - vamwe vanhu vari dzimwe nguva vakavhiringidzika ari mhedziso. Somuenzaniso, sezvo vakawanda Coriolis simba chokuita mananara dzinofamba mumakungwa uye mhepo, paIndaneti unogona kuwana vanoti kuti kurerutsa enzizi kuchamhembe hemisphere kunoitika kurudyi, uye mune Southern scouring zviito mvura runonyanya pamahombekombe kuruboshwe. Vamwe vanoti chiitiko ichi pave Coriolis simba. vavengi vavo tsanangura zvimwe zvose: kubva vachishandisa kutenderera nyika yacho paasingazonyuri runoita zvishoma nokukurumidza (zvishoma inertia) pane kurema mvura uye nokuda musiyano uyu kuzvitsinhanisa. Kunyange zvazvo vamwe pezvakaitwa kuitika mugungwa, chaizvoizvo, "mhosva" zviri Coriolis simba. Difficulty kuziva kubvira zvakawanda zvimwe zvinofurira. Coriolis kuratidzwa sezvo simba regiravhiti kudyidzana nekugona.

Rega kutsanangura mhando ipi simba, uye nei akadaro kufarira. Sezvo redu rinogona kunzi asiri inertial maitiro (chichifamba uye tenderera), ipapo chero muitiro, vaionekwa pazvinhu kwairi, vanofanira kufunga inertia. Kazhinji kushandiswa kutsanangura zvakavamba kuchinja ino chaiyo kureba kupfuura 50 M uye uremu wezviuru makirogiramu. Uyezve, imwe hwakanyatsorwisa mira mucherechedzi amire pasi ndege umo zvakavamba kuchinja ndatsamwa rotates circumferentially. Kana kukosha rotational kumhanya panyika yaizova kupfuura nguva oscillation pakati zvakavamba kuchinja, notional ndege yayo zvichakurukurwa misha nenzira kuchamhembe hemisphere, kutenderera ari zvakashandurwa, uri mberi maawa divi. Asiwo, kuwedzera nguva iri kupfuura pasi kutenderera mwero kuchaguma iya yakananga kufamba Kutenderera. Izvi zvinoitika nokuti kuti vachishandisa kutenderera nyika munyika pave rotational kumhanyisa pakati zvakavamba kuchinja, mumwe Vector iyo vachambokanganwa kuti rinopfungaira ndege.

Kutsanangura, unogona kushandisa muenzaniso upenyu. Zvechokwadi, chimwe nechimwe semwana akatasva carousel, chinova kutenderera neumwe chisina kutsetseka velocity guru disk. Fungidzira mbiri pfungwa pamusoro Disc, mumwe pedyo nechepakati akabatana (A) uye wechipiri - on pedo pamupendero kuti nharaunda (B). Kana munhu Panguva A, anosarudza kutamira nguva B, zvino, panguva Pakutanga, kupfuura Zvakanyanya Kunaka Panguva Yepamuviri inofamba nzira iri achirurama mutsetse A-B zvamazvirokwazvo denderedzwa nharaunda. Asi danho mumwe munhu pfungwa B iri haachatauri, sezvo Disc iri kugadzira. Somugumisiro, kana tikaramba zvinokambaira vakaronga mutsetse-nharaunda, kuti kana nharaunda yacho pfungwa B, rakanga risisiri vaizova nokuda kutsvetera. Kana vanhu anogadzirisa nzira yavo maererano chaiko mamiriro B, ipapo trajectory kuuya munhu curved mutsetse, sefungu, kumusoro uko kunangana kutungamirirwa kutenderera. Zvisinei, pane nzira kuti kubva A kuenda B ari yakarurama mutsetse: zvakafanira kuwedzera kumhanya kufamba, kutaura muviri (munhu) kumhanyisa. With kuwedzera mufambo A-B kuramba ari rectilinear sangano zvakafanira kune zvose kuwedzera kufamba kweropa unodiwa. Musiyano inotsanangurwa nemashoko Centrifugal simba iri kuti akananga yokupedzisira rinobatana pamwe nharaunda pamusoro kutenderera sekamufarenzi.

Saka, kutamira ari kutenderera chinhu ane zvinokonzerwa Coriolis simba. The yemaitiro zvinoreva:

F = 2 * V * M * cosFi,

apo M - guru pakati zvinofamba muviri; V - kumhanya kufamba; cosFi - ukoshi izvo anofunga pakona pakati nhungamiro rwokufamba akabatana kuti kutenderera.

Kana, mune vector kumiririrwa:

F = - M * a,

uko - kumhanyisa pamusoro Coriolis. "-" chiratidzo zvauya nokuti simba kubva zvinofamba muviri negwara.
