Qhov instant nruab nrab ntawm kev sib hloov, kuj hu ua tam sim ntawd velocity center, los yog tam sim ntawd center los yog instant center, yog lub ntsiab lus kho rau lub cev nyob rau hauv lub hom phiaj ntawm lub zog uas muaj xoom tshaj tawm ntawm ib qho instant ntawm lub sij hawm.

Dhau li ntawd, dab tsi yog qhov txawv ntawm instantaneous Centres?

Nws tuaj yeem kho, ruaj khov lossis hloov pauv

  • Tsau IC tam sim no thaum qhov txuas txuas ncaj qha & ib qho ntawm cov kev sib txuas yuav nyob ruaj khov / kho.
  • Kev ruaj ntseg IC yog tam sim no thaum qhov txuas txuas los ntawm tus pin sib koom ua ke & nyob rau hauv kev txheeb ze.

Ib yam li ntawd, lub dav hlau dav dav yog dab tsi? General kev npaj tsab ntawv tsa suab tso cai rau ib txhij rotational thiab translational tsab ntawv tsa suab hauv 2-D dav hlau . Cov tsab ntawv tsa suab ntawm lub cev nruj tej zaum yuav piav raws li ib qho yooj yim superposition ntawm lub cev txhais lus thiab kev sib hloov raws li qhia hauv daim duab hauv qab no.

Qhov sib thooj, Kennedy's Theorem yog dab tsi?

Kennedy's Theorem . Kennedy's theorem txheeb xyuas cov cuab yeej tseem ceeb ntawm peb lub cev nruj hauv kev txav. Peb lub chaw instantaneous sib koom los ntawm peb lub cev nruj hauv kev sib txheeb ze rau ib leeg txhua tus pw ntawm tib txoj kab ncaj nraim.

Lub Center ntawm kev sib hloov yog dab tsi?

Nrog rau txhua qhov kev sib hloov, muaj ib qho chaw ruaj khov-hu ua qhov chaw ntawm kev sib hloov - nyob ib ncig ntawm uas txhua yam rotates. Los yog lub ntsiab lus tuaj yeem nyob sab nraud ntawm daim duab, nyob rau hauv rooj plaub no tus duab txav raws ib ncig arc (xws li lub orbit) nyob ib ncig ntawm qhov chaw ntawm kev sib hloov . Tus nqi tig yog hu ua kev sib hloov lub kaum sab xis.
