Ii-hydraulic jacklihlanganisa igama elithi “four-two-donsa inkulungwane yamakati” ngokucacile nangokucacile. Ujeke omncane unesisindo esingeqile kwamakati ambalwa kuya kwamakati ambalwa, kodwa angaphakamisa amathani ambalwa noma ngisho namakhulu amathani ezinto ezisindayo. Kuyinto engakholeki ngempela. Khona-ke, yini ingaphakathi le-hydraulic jack energy?

I-Hydraulic jack ingumkhiqizo we-classical physics. Nakuba simangazwa ukuhlakanipha komuntu, kuyadingeka ukuqonda isimiso sokusebenza se-hydraulic jack. Ngakho-ke namuhla, ngizokunikeza ukuhlaziywa okulula ngokombono we-physics. Amajekhi we-Hydraulic.
Okokuqala, kufanele siqonde ithiyori yakudala kumakhenika asendulo, okungukuthi, umthetho kaPascal, umthetho kaPascal, ongumthetho we-hydrostatics. “Umthetho KaPascal” uthi ngemva kwanoma yiliphi iphuzu oketshezini olumile olungenakucindezelwa likhiqiza ukwanda kwengcindezi ngenxa yamandla angaphandle, lokhu kukhula kwengcindezi kuzodluliselwa kuwo wonke amaphuzu oketshezi olumile ngokuphazima kweso.

Ingaphakathi likajekhi we-hydraulic ngokuyinhloko liyisakhiwo esimise u-U lapho ipiston encane ixhunywe ku-piston enkulu futhi efana nedivaysi yokuxhumana. Umfutho we-hydraulic we-piston enkulu ukhuphuka ngokucindezela i-lever yesandla exhunywe ku-piston encane ukuze udlulisele uketshezi ku-piston enkulu. Ngalesi sikhathi, abanye abantu bangase bangaqondi. Amathani wamandla ambalwa asancike kubantu abasebenzisa ingcindezi efanayo ukuze baqedele ukuphakamisa?
Vele akunjalo. Uma kunjalo, khona-ke ukuklama kwalokhui-hydraulic jackakusho lutho. Isebenzisa umthetho kaPascal ku-physics. Isilinganiso sendawo yokuxhumana yamapiston amakhulu namancane kuketshezi silingana nesilinganiso sokucindezela. Uma sicabanga ukuthi amandla esandleni akhuphuka izikhathi ezingu-20 ngokucindezela i-lever ku-piston encane, futhi isilinganiso sendawo yokuxhumana yama-pistons amakhulu namancane ngu-20: 1, khona-ke ukucindezela okuvela ku-piston encane kuya ku-piston enkulu kuzophindeka kabili. kuya ku-20*20=400 izikhathi. Sizosebenzisa ukucindezela kwe-30KG ukuze sicindezele i-lever yesandla, amandla e-piston enkulu azofinyelela ku-30KG * 400 = 12T.

Ukudluliswa kwamandla okuphansi, ngaphansi kwesenzo sesimiso sikaPascal, kungaba khona i-flyover esheshayo yekhwalithi, ukuze kuzuzwe ukuguqulwa kwamandla okuphezulu. Yingakho ujeke omncane we-hydraulic uqukethe inani elikhulu lamandla.
