Ingilazi iyinto eqinile futhi ephukayo.Kodwa-ke, inqobo nje uma incibilika ekushiseni okuphezulu bese idonswa ngokushesha ngezimbobo ezincane ibe imicu yengilazi emihle kakhulu, impahla iguquguquka kakhulu.Okufanayo kuyingilazi, kungani ingilazi ye-block evamile iqinile futhi i-brittle, kuyilapho ingilazi ene-fibrous iguquguquka futhi iguquguquka?Lokhu empeleni kuchazwa kahle ngezimiso zejometri.

Cabanga ukugoba induku (ucabanga ukuthi akukho ukuphuka), futhi izingxenye ezihlukene zenduku zizokhubazeka zibe ngamazinga ahlukahlukene, ikakhulukazi, uhlangothi olungaphandle lunwetshiwe, uhlangothi lwangaphakathi lucindezelwe, futhi ubukhulu be-axis cishe abushintshi.Uma igotshwe nge-engeli efanayo, induku iba mncane, ingaphandle inwetshwa kancane futhi ingaphakathi licindezelwe kancane.Ngamanye amazwi, okuzacile, kuba ncane izinga le-tensile yendawo noma ukuwohloka kokucindezela kwezinga elifanayo lokugoba.Noma iyiphi impahla ingangena ezingeni elithile lokuguquguquka okuqhubekayo, ngisho nengilazi, kodwa izinto eziphukayo zingamelana nokuwohloka okuncane kakhulu kunezinto ezidonsayo.Lapho i-fiber yengilazi incane ngokwanele, ngisho noma izinga elikhulu lokugoba livela, izinga le-tensile yendawo noma i-compressive deformation lincane kakhulu, elingaphakathi kwebanga lokuthwala lempahla, ngakho-ke ngeke liphule.

Kuyabonakala ukuthi ukuqina kanye nokuqina kwezinto ezibonakalayo akuphelele.Ukusebenza kokuqukethwe akuhlobene kuphela nokwakheka kwayo kwangaphakathi kanye nesakhiwo, kodwa futhi nesikali sayo.Ngaphezu kwalokho, kubuye kuhlotshaniswe nezici ezifana nendlela yamandla.Isibonelo, izinto eziningi zisebenza njengoketshezi ngaphansi kwemiphumela yangaphandle ehamba kancane, futhi ziziphatha njengemizimba eqinile ngaphansi kwemiphumela yangaphandle esheshayo.Ngakho-ke, ukusetshenziswa okuqondile noma izimo ezithintekile nazo zidinga ukucatshangelwa lapho kuhlaziywa izakhiwo zezinto ezibonakalayo.
