Ib lub tswv yim yooj yim heev thaum cuam tshuam nrog zog yog lub tswv yim ntawm kev sib npaug los yog tshuav nyiaj li cas. Yog qhov loj thiab kev taw qhia ntawm lub zog ua yeeb yam ntawm ib yam khoom yog qhov sib npaug, ces tsis muaj net zog ua yeeb yam ntawm cov khoom thiab cov khoom yog hais tias nyob rau hauv kev sib npaug.

Tsis tas li ntawd, koj yuav nrhiav tau lub zog sib npaug li cas?

Yog qhov khoom nyob ntawm kev sib npaug , ces net zog ua raws li qhov khoom yuav tsum yog 0 Newton. Yog li, yog tag nrho cov zog yog ntxiv ua ke ua vectors, ces tus resultant zog (tus vector sum) yuav tsum yog 0 Newton.

Cov xwm txheej rau equilibrium yog dab tsi? Ib yam khoom nyob hauv kev sib npaug yog; Lub resultant quab yuam ua rau cov khoom yog xoom. Tus lej ntawm lub sijhawm ua haujlwm ntawm ib qho khoom yuav tsum yog xoom.

Yog li ntawd, txoj cai sib npaug hais li cas txog lub zog?

yog li cov khoom uas muaj qhov nrawm nrawm kuj muaj xoom net sab nraud zog . Qhov no txhais tau tias tag nrho cov zog ua ntawm cov khoom yog sib npaug - uas yog hais , lawv nyob hauv kev sib npaug . Qhov no txoj cai kuj tseem siv tau rau kev txav mus rau hauv ib qho kev taw qhia tshwj xeeb. Xav txog ib qho khoom txav raws li x-axis.

3 hom equilibrium yog dab tsi?

Muaj peb hom equilibrium : ruaj khov, tsis ruaj khov, thiab nruab nrab. Cov duab thoob plaws qhov module no qhia txog ntau yam piv txwv.
