A. Isishwankathelo sokuhamba kwenkqubo
Ukuqengqeleka okushushu (ityhubhu yentsimbi engenamthungo) : ityhubhu engqukuva → ukufudumeza → ukugqobhoza → ukuqengqeleka okuthathu okuphezulu, ukuqengqeleka okuqhubekayo okanye ukukhutshwa → ukukhutshwa kwetyhubhu → ukulinganisa (okanye ukunciphisa) → ukupholisa → ibhilethi → ukolula → uvavanyo lwe-hydrostatic (okanye ukubhaqa isiphene) → ukuphawula → ugcino.
Ityhubhu yentsimbi ebandayo (eqengqelekayo) engenamthungo: ityhubhu yetyhubhu engqukuva → ukufudumeza → ukugqobhoza → isihloko → ukuqhola → ukuchola → ukugqunywa kweoyile (iplate yobhedu) → umzobo obandayo ohamba ngeendlela ezininzi (ukuqengqeleka okubandayo) → ibhilethi → unyango lobushushu → ukulungisa → uvavanyo lwe-hydrostatic (ukubona iziphene) → ukuphawula → ugcino.
