Lub perpendicular axis theorem hais tias moment ntawm inertia ntawm lub phiaj xwm lamina(piv txwv li 2-D lub cev) txog ib qho axis perpendicular rau lub dav hlau ntawm lamina yog sib npaug rau sum ntawm lub sij hawm ntawm inertia ntawm lub lamina hais txog ob axes ntawm txoj cai kaum rau ib leeg, nyob rau hauv nws tus kheej lub dav hlau intersecting ib leeg ntawm lub point …

Yuav ua li cas yog tus qauv ntawm txoj kev xav ntawm qhov perpendicular?

xav tias peb xav xam lub sijhawm ntawm inertia ntawm lub nplhaib sib xws txog nws txoj kab uas hla. Cia nws qhov chaw yog MR²/2, qhov M yog qhov loj thiab R yog lub vojvoog. Yog li, los ntawm txoj kev xav ntawm perpendicular axes, IZ= Ix + y Vim lub nplhaib sib xws, txhua txoj kab uas hla yog sib npaug.∴ Ix=Iy

Yuav ua li cas yog tus qauv siv tau rau txoj kev xav ntawm lub kaum sab xis?

M. O. I ntawm lub cev txog ib qho axis dhau los ntawm nws yog sib npaug rau qhov sib npaug ntawm M. O. I ntawm lub cev txog 2 kev sib nrig sib txuas ntawm cov axes nyob hauv lub dav hlau ntawm cov khoom. md2=Added M. O. I vim qhov kev ncua deb ntawm O thiab C. Qhov kev xav no siv tau rau txhua yam khoom.

Dab tsi yog qhov theorem ntawm perpendicular thiab parallel axis?

Lub parallel axis theorem hais tias, lub sijhawm ntawm inertia ntawm lub cev txog ib qho axis yog sib npaug rau lub sijhawm ntawm inertiatxog qhov sib npaug ntawm nws qhov nruab nrab ntawm qhov loj ntxiv rau cov khoom ntawm qhov loj ntawm lub cev thiab lub square ntawm qhov kev ncua deb ntawm ob qho tib si axes.

Yuav ua li cas koj ua pov thawj qhov perpendicular axis theorem?

State and Prove Theorem of Perpendicular Axis

Perpendicular axis theorem nqe lus - Lub perpendicular axis theorem hais tias moment of inertia, rau txhua axis uas yog perpendicular rau lub dav hlau, yog sib npaug rau cov lej ntawm ob qho tib si perpendicular axes ntawm lub cev uas cuam tshuam nrog thawj axis.
