Ib phau ntawv dag ntawm kab rov tav yog ib qho piv txwv ntawm ruaj khov equilibrium . Yog tias phau ntawv raug tshem tawm ntawm ib ntug thiab tom qab ntawd tso cai rau poob, nws yuav rov qab los rau qhov qub. Lwm yam piv txwv ntawm ruaj khov yog lub cev pw hauv pem teb xws li lub rooj zaum, rooj thiab lwm yam.

Kuj paub, qhov sib npaug ruaj khov yog dab tsi?

Kev txhais ntawm ruaj khov equilibrium .: ib state kev sib npaug ntawm lub cev (xws li lub pendulum dai ncaj qha los ntawm nws qhov kev txhawb nqa) xws li thaum lub cev hloov chaw me ntsis nws zoo li rov qab mus rau nws txoj haujlwm qub- piv tsis ruaj khov kev sib npaug.

Tom qab ntawd, lo lus nug yog, ua li cas koj ua tiav kev sib npaug? Thaum tus nqi xav tau sib npaug ntawm tus nqi muab, ces ua lag luam kev sib npaug (aka Supply-xav tau kev sib npaug ) yog ua tiav , qhov ntau npaum li cas sib npaug kev sib npaug kom muaj nuj nqis thiab tus nqi sib npaug ntawm kev sib npaug nqe.

Qhov thib ob, koj txhais li cas los ntawm qhov sib npaug thiab tsis ruaj khov?

Equilibrium yog lub xeev ntawm ib qho system uas ua tsis hloov. Ib kev sib npaug raug txiav txim siab ruaj khov (rau simplicity peb yuav xav txog asymptotic ruaj khov tsuas yog) yog tias lub kaw lus ib txwm rov qab los rau nws tom qab muaj kev cuam tshuam me me. Yog hais tias lub system txav deb ntawm lub kev sib npaug tom qab me me cuam tshuam, ces tus kev sib npaug yog tsis ruaj khov.

Lub hauv paus ntsiab lus ntawm equilibrium yog dab tsi?

Ob peb yam txoj cai equilibrium yog: twoforce txoj cai : Hais tias yog ob lub zog nyob hauv kev sib npaug lawv yuav tsum sib npaug, opposite thiab collinear. Peb lub zog txoj cai : Hais tias yog peb lub zog nyob rau hauv kev sib npaug tom qab ntawd qhov tshwm sim ntawm ob lub zog yuav tsum sib npaug, sib npaug thiab sib npaug nrog lub zog thib peb.
