Ntawm no lub sij hawm ntawm inertia ntawm cov khoom yog feem ntau tas mus li los ntawm kev siv lub torque. Yog li, yog hais tias muaj ib tug net torque ces, nws txhais tau hais tias khoom rotates nrog tas li angular acceleration thiab li no nws angular tshaj tawm yuav nce.
Yuav ua li cas thaum ib yam khoom tab tom ntsib lub net torque?
Torque yog qhov sib npaug sib npaug ntawm lub zog. Yog li, lub net torque yuav ua rau ib qho khoom tig nrog kev nrawm nrawm. Vim tias txhua qhov kev hloov pauv muaj qhov axis ntawm kev sib hloov, lub torque yuav tsum tau txhais hais txog kev hloov axis. Lub torque yog ib qho quab yuam siv rau qhov taw tes ntawm ib qho khoom hais txog lub axis ntawm kev sib hloov.
Thaum twg ib yam khoom tab tom ntsib lub net torque nws nyob rau hauv dynamic equilibrium?
Rau qhov khoom kom muaj kev sib npaug, nws yuav tsum tau ntsib tsis muaj kev nrawm. Qhov no txhais tau hais tias ob qho tib si lub zog net thiab net torque ntawm cov khoom yuav tsum yog xoom.
Net torque yog dab tsi?
Lub net torque yog qhov sib npaug ntawm tus kheej torques . Rotational Equilibrium yog analogous rau translational equilibrium, qhov sum ntawm cov rog yog sib npaug zos rau xoom.
Thaum lub net torque siv rau ib yam khoom nws tsim ib?
A net torque siv rau ib qho khoom ua rau: lub angular tshaj tawm ntawm cov khoom hloov.

Leej twg muab khoom plig Nobel Peace yam khoom plig?
Hauv Oslo qhov khoom plig Nobel Peace yog nthuav tawm los ntawm tus Thawj Tswj Hwm ntawm Norwegian Nobel Committee nyob rau hauv lub xub ntiag ntawm Lawv Majesties huab tais thiab poj huab tais ntawm Norway, tsoom fwv, Storting cov neeg sawv cev thiab ib tug caw cov neeg tuaj saib.
Thaum lub hli ci ntsa iab tab tom xaws hnyav thiab xis nyob?
Cov neeg thom khwm zoo siab thaum kaj ntug, lawv lub siab muaj zog thiab txaus siab rau yav tav su, tab sis lawv dhau los ua สงบ thiab hnyav thaum hmo ntuj. Lawv lub siab xav qhia txog cov ris tsho uas lawv xaws thiab rau tus uas lawv xaws. Vim li cas cov yoj yij thiaj li hnyav rau lub hli?
Thaum ib yam khoom uas tsis yog tib neeg muab rau tib neeg tus yam ntxwv?

Thaum cov kws lag luam lag luam tab tom kos cov piv txwv ntawm kev thov thiab cov khoom siv?
Thaum cov kws lag luam lag luam tau kos cov piv txwv ntawm kev thov thiab muab khoom nws yog ib qho kev kos duab qhov kev thov lossis cov khoom siv nkhaus uas nyob ze rau kab rov tav? Thaum cov kws tshawb nrhiav nyiaj txiag tau kos cov piv txwv ntawm qhov kev thov lossis cov khoom siv nkhaus uas nyob ze rau kab rov tav, lawv xa mus rau qhov kev thov lossis cov khoom nkhaus raws li elastic.
Thaum muag ib lub tsev dab tsi yog cov khoom siv thiab khoom siv?
Fixtures yog cov khoom uas txuas nrog rau cov khoom; tsau, yog koj yuav. Fittings yog cov khoom uas tsis txuas nrog cov cuab yeej, tshwj tsis yog los ntawm cov ntiv tes xoos (lossis ntau dua, cov ntsia hlau). Cov khoom siv thiab khoom siv dab tsi suav nrog hauv tsev muag?
