Inqwaba yeshiti yentsimbi
Iinqwaba zamaphepha ziindawo ezinde zesakhiwo ezinenkqubo yokutshixa ethe nkqo eyenza udonga lwe-diaphragm.
Iindonga zihlala zisetyenziselwa ukugcina umhlaba okanye amanzi. Ukusebenza kwecandelo leenqwaba zamaphepha kuxhomekeke kwijiyometri yalo kunye nomhlaba elibethelelwa kuwo.
Inqwaba idlulisela uxinzelelo oluvela kwicala eliphezulu lodonga ukuya kumhlaba ophambi kodonga.
Kwizinto ezipakishwayo, iinqwaba zamaphepha eziqengqelekayo ezishushu kunye neenqwaba zamaphepha ezenziwe ngokubanda zezona ndlela zimbini ziphambili zokwenza iinqwaba zamaphepha. Nangona kukho umahluko phakathi kwezi ndlela zimbini, umahluko obalulekileyo kukudibanisa.
Ngenxa yokuba iinqwaba zamaphepha eziqengqelekayo ezishushu zenziwe ngentsimbi eshushu kakhulu, ii-interlocks zihlala ziqinile kuneenqwaba zamaphepha ezenziwe ngokubanda.
Ngokubanzi, ukutshixa okukhululekileyo akukhuthazwa kwiimeko ezinzima kakhulu zokuqhuba okanye eludongeni apho kufuneka ukungena kwamanzi okuphantsi. Ngaphandle koko, ezi ntlobo zimbini zamacandelo zisebenza ngendlela efanayo.
