General Planar motion 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.

Tsis tas li ntawd, lub ntsiab lus ntawm kev txav txav yog dab tsi?

Plane Motion . tus tsab ntawv tsa suab ntawm lub cev nruj xws li tias tag nrho nws cov ntsiab lus txav mus rau qhov sib npaug rau qee qhov ruaj dav hlau . Xws li tsab ntawv tsa suab yog tsim los ntawm translational tsab ntawv tsa suab ua ke nrog ib tug arbitrarily xaiv ncej nyob ib ncig ntawm uas rotational tsab ntawv tsa suab tshwm sim.

Qhov thib ob, lub dav hlau dav dav yog dab tsi? dav dav dav Cov lus tsa suab tshwm sim thaum lub cev tsis muaj zog tau txais kev txhais lus thiab kev sib hloov ib txhij. Koj tuaj yeem txheeb xyuas qhov teeb meem zoo li no los ntawm kev siv qhov kev tshuaj ntsuam xyuas qhov tseeb lossis kev txheeb xyuas qhov txheeb ze.

Tib neeg kuj nug tias, lub cev planar yog dab tsi?

Ntawm no yog ib phau ntawv sau rau ntawm kev npaj dynamics ntawm nruj cev . Thaum peb hais kev npaj dynamics, peb tab tom xa mus rau dynamics ntawm cev uas tsuas tuaj yeem tig txog ib qho axis (perpendicular rau "dav hlau"). Kinetic zog ntawm ib tug nruj lub cev (derivation tuaj). Angular momentum ntawm ib tug nruj lub cev (derivation tuaj).

Dab tsi yog kev taw qhia dav dav hauv kev ua si nawv?

Cov lus tsa suab yog ib qho kev sib txuas ntawm linear thiab rotary kev tawm suab . Cov lus tsa suab yog hom ntau tshaj plaws kev ua si hauv kev ua si nawv thiab kev tawm dag zog lub cev. Hauv qhov no, lub cev txav mus rau hauv linear tsab ntawv tsa suab raws li qhov tshwm sim ntawm rotary kev tawm suab ntawm tus kheej ntu ntawm extremities. Caij tsheb kauj vab yog lwm qhov piv txwv ntawm kev taw qhia dav dav.
