Ibhalansi yomatshini

Kwi-Newtonian mechanics, ngokukodwa kwi-statics, inkqubo kuthiwa i-equilibrium equilibrium xa iimali zazo zonke imikhosi yangaphandle kunye nayo yonke i-mechanic moments yangaphandle i-zero.

Kwiifomula:

${\begin{cases}\sum \mathbf {F} ^{(e)}=0\\\sum \mathbf {M} ^{(e)}=0\end{cases}}$

I-equation yokuqala imisela Template:' loguqulelo lwenkqubo, ekubeni, ngomthetho wesibini kaNewton, oko kuthetha ukuba ukukhawuleza kombindi wobunzima ngu-zero. Eyesibini endaweni yoko imisela ukulingana okujikelezayo Template:', kuba kuthetha ukuba ukukhawuleza kwe-angular yi-zero, ngenxa ye-cardinal umthetho wesibini.

Enye ingcaciso ithi inkqubo ikwi-equilibrium yomatshini ukuba indawo yayo kwindawo yoqwalaselo ikwindawo apho i- gradient yamandla enokubakho inguziro.
