Mfundo Yogwira Ntchito:
Ma Jacks amagawidwa m'makondo a jack ndi ydraulic, iliyonse yokhala ndi mfundo zosiyanasiyana. Mwakutero, mfundo yofunika kwambiri yomwe ikufalitsa matenda a hydraulic ndi lamulo la Pascal, zomwe zikutanthauza kuti kukakamizidwa kwamadzi kuli yunifomu kulikonse. Mwanjira imeneyi, mu dongosolo loyenerera, kupanikizika komwe kumagwiritsidwa ntchito piriti yaying'onoyo ndi yaying'ono, pomwe kupanikizika kwa piston yokulirapo kulinso kwakukulu, komwe kumatha kukhalabe ndi maziko amadzimadzi. Chifukwa chake kudzera kusamutsa madzi, zovuta zosiyanasiyana zitha kupezeka kumapeto kosiyanasiyana, kukwaniritsa cholinga chosintha. The Hydraulic wamba Jack amagwiritsa ntchito mfundo imeneyi kuti mukwaniritse mphamvu yotumiza mphamvu. The screw Jack imagwiritsa ntchito lever kuti mutulutse chovalacho, chomwe chimakankhira chilolezo cha ratchet kuti chizungulira. Zingwe zazing'ono za maambulera yayikulu imayendetsa ma ambudzi akuluakulu, ndikupangitsa kuti mawonekedwe azithamangitsidwa, potero kupangitsa kuti nyali yokweza inyamule kapena kutsika, kukwaniritsa ntchito yakuwoneka ndi mavuto. Komabe, sizophweka ngati jack ya hydraulic jack.
