Chofunikira Choyesa

Kuphatikiza pakuwonetsetsa kapangidwe ka mankhwala ndi makina amakina, chitoliro chachitsulo chokulungidwa mwachindunji ndi ingot chiyenera kuyang'aniridwa ndi mphamvu zochepa, ndipo kuyendera kwa eddy panopa kapena kuyang'ana kwa maginito kutayikira kungagwiritsidwe ntchito m'malo mwa kuyesa kwa hydraulic.

Kupereka Mphamvu
