Yenza lokhu kuhlola okulandelayo.
Lengisa isisindo ku-dynamometer bese uqopha isisindo esikhonjiswe yi-dynamometer. Okulandelayo, beka isisindo emanzini bese uqopha isisindo esikhonjiswe yi-dynamometer.
Qhathanisa izilinganiso zakho. Ingabe isisindo sikhulu uma sisemanzini noma uma singekho emanzini? Kungani? Xoxa ngemiphumela yalolu cwaningo nomlingani wakho.
Uma ukuhlolwa kwenziwa ngendlela efanele, imiphumela izobonisa ukuthi isisindo somthwalo siphansi uma umthwalo usemanzini. Kwenzeka into efanayo uma uphakamisa into emanzini bese uyikhipha kuyo. Into ephakanyisiwe emanzini izwakala ilula kunesisindo esifanayo esikhushulwe emanzini. Isisindo siphansi uma umthwalo usemanzini, noma into ephakanyisiwe emanzini izwakala ilula ngenxa yamandla okuntanta asebenza entweni.
Ukuqonda Ukuqina
Ukuqina amandla avelayo noma amandla aphelele aqondiswa phezulu akhishwa uketshezi entweni lapho into isemanzini. Ama-fluid yizinto ezingageleza, isibonelo umoya namanzi.
Ifomula Yamandla Okuqina
Uma into isemanzini, amanzi angaphezulu ayayisunduza into phansi kanti amanzi aphansi ayayisunduza into phezulu.
Ubukhulu bamandla okuqina:
Imininingwane:
(rho) = Ubuningi bamanzi (Kg/m3), g = Ukusheshisa ngenxa yamandla adonsela phansi (9,8 m/s2), V = Umthamo wento ecwiliswe emanzini (m3), A = Indawo engaphezulu kwento (m2), h = h2 - h1 = Umehluko ekujuleni koketshezi olungaphezulu nangaphansi kwento ecwiliswe emanzini (m)
Uketshezi (amanzi) olujulile ngo-h2 inamandla okucindezela noma okucindezelayo amakhulu kunoketshezi (amanzi) ekujuleni kwe-h1Umehluko ekucindezelweni noma ekucindezelweni udala amandla aphelele aqondiswa phezulu. Uketshezi (amanzi) ngakwesobunxele nangakwesokudla sento lunokujula okufanayo ngakho amandla avelayo alingana no-zero.
