yuav ua li cas xam pob zeb ceev

Qhov ceev ntawm lub pob zeb, feem ntau hu ua qhov ceev tseem ceeb, yog suav nrog cov qauv. Qhov kev ceev tseem ceeb no tuaj yeem suav tau los ntawm kev siv lub hauv paus square ntawm lub vojvoog ntawm lub zeb (hauv metres) muab faib los ntawm lub gravitational acceleration (9.81 m / s^2) thiab muab nws los ntawm qhov tsis tu ncua, feem ntau ntawm 0.5 thiab 0.75, nyob ntawm seb hom zeb thiab qhov loj ntawm cov xov xwm.

Cov mis rau xam qhov tseem ceeb ceev ntawm lub pob zeb yog:

Ntawm no yog ib qho kev faib ntawm cov khoom:

Radius ntawm lub zeb: Qhov no yog qhov kev ncua deb ntawm qhov nruab nrab ntawm lub zeb mus rau sab nraud ntawm lub zeb.

Gravitational acceleration (g): Qhov no feem ntau yog siv li 9.81 m / s29.81m / s2.

Tsis tu ncua: Qhov no tsis tu ncua yog feem ntau ntawm {{0}}.5 thiab 0.75, nyob ntawm seb hom zeb thiab qhov loj ntawm cov xov xwm. Rau feem ntau mills, tus nqi ntawm ib ncig ntawm 0.65 feem ntau yog siv.

Thaum koj muaj cov txiaj ntsig no, ntsaws rau hauv cov qauv kom pom qhov nrawm nrawm.

Piv txwv li, cia peb hais tias koj muaj lub pob zeb nrog lub vojvoog ntawm 1 meter thiab koj xav suav nws qhov nrawm nrawm uas siv qhov tsis tu ncua ntawm 0.65:

Qhov no txhais tau hais tias thaum lub pob zeb tig ntawm qhov ceev ntawm kwv yees li 3.88 meters ib ob, lub zog centrifugal ntawm cov pob hauv lub zeb yuav sib npaug rau lub zog gravitational, tso cai rau cov khoom tuav tawm tsam sab hauv phab ntsa ntawm lub zeb thiab tiv thaiv kom tsis txhob poob. Qhov ceev no yog qhov tseem ceeb rau kev ua haujlwm zoo ntawm lub zeb thiab kom ua tiav cov txiaj ntsig zoo sib tsoo.
