Isebenza njani iHydraulic System
Imigaqo eSisiseko yeNkqubo yeHydraulic (uMthetho kaPascal)
Isixokelelwano samanzi aphantsi komhlaba sisebenza ngokusekwe kuMthetho kaPascal, umgaqo osisiseko kubuchwephesha bolwelo. UMthetho kaPascal uthi xa uxinzelelo lusetyenziswa kulwelo oluvaliweyo, uxinzelelo luhanjiswa ngokulinganayo kuwo onke amacala kulo lonke ulwelo. Lo mgaqo uvumela iinkqubo zehydraulic ukuba ziphindaphinde amandla kwaye zenze ukuphakamisa okunzima kunye negalelo elincinci.
Umzekelo, xa umntu efaka amandla kwipiston encinci, uxinzelelo oluveliswa kulwelo luhamba ngemibhobho kunye nemibhobho ukuya kwipiston enkulu. I-piston enkulu, enommandla omkhulu, ivelisa amandla amakhulu kakhulu okuvelisa. Ubudlelwane phakathi kwegalelo kunye namandla okuphuma kuxhomekeke kumlinganiselo weendawo zepiston. Ukuba i-piston yegalelo inommandla we-square centimeters kunye ne-piston ephumayo inendawo ye-square centimeters, amandla okukhutshwa aya kuba phindwe kashumi kumandla okufakwayo, ucinga ukuba uxinzelelo olufanayo lusetyenziswa.
