Lub zog nyob rau hauv lub circumferential li feem ntau tshwm sim curvilinear tsab ntawv tsa suab

Los ntawm nws tus kheej, rau lub voj voog yog ib tug qhov chaw ntawm enigmas, raws li zoo raws li lawv muaj tswv yim daws teeb meem. Qhov no xam yog siv raws li lub feem ntau nquag siv lub cim ntawm nyob mus ib txhis. Feem ntau nyob rau hauv lus tsis sib xws rau cov square voj voog. Los ntawm ib ncig inextricably txuas rau cov duab ntawm lub log thiab yeej tsab ntawv tsa suab. Nyob rau hauv tus txheej txheem no, tus poj minds ntawm tib neeg, tsis tsuas pom embodied nyob rau hauv lub neej ntawm cov kev cai ntawm mechanics, thiab ib tug philosophical kev txiav txim zoo rau qhov rov qab mus rau nws tus kheej.

Nyob rau hauv pre-Christian lub sij hawm rau cov nqe lus txuam kos npe rau-log hnub. Ib txhia xav pom nyob rau hauv lub disk embodiment ntawm kev txom kab, thiab lub zog point ntawm lub vajvoog yog ib tug perpetual txheej txheem. Astrology vajvoog pom ib tug kos npe rau ntawm lub zodiac tsim ib txoj kab. Ouroboros - nab uas tom nws tus kheej tus Tsov tus tw, tsis tau ib zaug seb lub cim qhia hais tias lub zog ntawm lub vajvoog? Lej thiab qhov nyuab nyob rau hauv no geometric duab lurking kev txiav txim zoo, thiab physics, kawm yeej cov lus tsa suab, tsim ib tug haib platform rau theoretical piav qhia txog nws cov pa cai ntawm mechanics. Yuav luag raws nraim curvilinear tsab ntawv tsa suab yog feem ntau. zog ntawm lub cev nyob rau hauv ib lub voj voog yog ib tug tshwj xeeb zoo tagnrho cov ntaub ntawv ntawm no multifaceted txheej txheem.

Xav ib tug nkhaus zog txoj kev muaj peev xwm nthuav nws raws li ib tug txheej ntawm arcs ntawm lub voj voog ntawm txawv radii. Raws li, raws li cov yeej cov lus tsa suab, curvilinear tsab ntawv tsa suab thiab ceev. Lub zog yeej ib txwm yuav siv sij hawm qhov chaw nyob rau hauv tus ntawm rog, thaum muaj ib tug tsis tu ncua hloov nyob rau hauv cov kev taw qhia ntawm cov tshaj tawm vector. Lub ntsiab mob ntawm curvilinear tsab ntawv tsa suab yog hais tias lub vector tshaj tawm los ntawm lub cev thiab ua yeeb yam rau nws yuav tau ib tug quab yuam qhia raws cov kab ncaj nraim uas sib tshuam. Nyob rau hauv sib piv rau lub rectilinear tsab ntawv tsa suab vectors ntawm kev quab yuam thiab tshaj tawm nyob rau hauv tib txoj kev coj.

Yog hais tias peb xav txog txawm niaj hnub tsa suab ntawm lub cev circumferentially, nws yog ua tau kom paub qhov txawv nws yooj yim zog thiab cov yam ntxwv. Firstly, nws yog ib qho piv txwv ntawm ib tug curvilinear tsab ntawv tsa suab nrog rau qhov tshaj tawm modulus. Secondly, peb yuav tsum tsis txhob hnov qab hais tias peb yuav soj ntsuam nrog ib tug acceleration, uas provokes ib qhov kev hloov ntawm cov kev taw qhia. Qhov no zoo ntawm acceleration yog hu ua "centripetal". Raws li cov classical txhais, nrog rau qhov no acceleration lub cev txav nyob rau hauv ib lub voj voog ntawm ib tus nqi tsis tu ncua modulus, thiab qhov no acceleration yog qhia raws li ib voos kheej-kheej ntawm lub vajvoog ntawm qhov chaw.

Raws li rau tus tshaj tawm vector, ntawm no peb yuav soj ntsuam nrog lub magnitude qhia rau ib tug tangent rau txoj kev. Nyob rau hauv cov ntaub ntawv ntawm lub zog nrog ib lub voj voog ntawm tus tshaj tawm vector thiab lub acceleration vector lub yog cuaj caum degrees. Xab cov kev ceev ntawm lub cev mus nyob rau hauv ib lub voj voog, siv tus qauv nqi sawv cev tus piv ntawm qhov kev ncua deb mus ncig los ntawm lub sij hawm. Xws li ib tug mus kom ze deb - nws yog tsis muaj dab tsi zoo li lub arc ntev. Nws kuj yuav siv lub angular xaav. Qhov no tej zaum yuav muab cov kev ntsuas ntawm degree ntawm lub kaum sab xis ntawm uas lub cev yuav ceev rau opredolonny lub sij hawm ntawm lub sij hawm, thiab nws yuav qhia nyob rau hauv radians los yog nyob rau hauv relation mus rau lub arc ntev mus rau lub voos kheej-kheej.

Muab lub constancy ntawm lub angular tshaj tawm nyob rau ncig tsab ntawv tsa suab ntawm lub cev, nws yog tsim nyog los noj mus rau hauv tus account ob peb ntau yam tias characterize no. Qhov no yog qhov zaus thiab sij hawm qhov tseem ceeb nyob ze zaus yog yeej ib txwm inversely xwm yeem mus rau lub sij hawm. Thaum lub sij hawm no yog hu ua lub sij hawm nyob rau hauv uas lub cev ua ib tug tag nrho tig, thiab ib zaus - lub xov tooj ntawm revolutions ib chav tsev lub sij hawm luv.

Txoj kev tshawb no ntawm lub cev nyob rau hauv ib lub voj voog ntawm kuj zoo kawg tswv yim tseem ceeb. Vim txawv cov cav tov thiab mechanisms yog tsis yooj yim sua yam uas tsis tau ib qho tseeb xam. Thiab tsuas ua tsaug rau cov kev cai ntawm mechanics yuav ua tau haum tseeb muab xam los ntawm txawv shafts, log, flywheels thiab lwm yam, uas abound nyob rau hauv niaj hnub cav tov thiab mechanisms.
