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:

$\{\begin{array}{c}\sum {𝐅}^{(e)}=0\\ \sum {𝐌}^{(e)}=0\end{array}$

I-equation yokuqala imisela iThemplethi:' loguqulelo lwenkqubo, ekubeni, ngomthetho wesibini kaNewton, oko kuthetha ukuba ukukhawuleza kombindi wobunzima ngu-zero. Eyesibini endaweni yoko imisela ukulingana okujikelezayo iThemplethi:', 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.
