Mayelana nentambo, ngokokuduka kwayo, ihlukaniswe ikakhulukazi yaba izinhlobo ezimbili, enye intambo eguquguqukayo, enye intambo emile.Abantu abaningi abayiqondi incazelo yangempela yentambo eguquguqukayo kanye nentambo emile, ngakho-ke i-Chenghua iyenza ngokuhambisana nokuphakama okuphezulu.Intambo yokuphepha yesibambi sokuwa izokunikeza isayensi edumile mayelana nentambo engashintshi kanye nentambo eguqukayo.
I-Ductility ingase iqondwe abantu abaningi, okungukuthi, intambo inganwetshwa ngaphansi kwesenzo samandla angaphandle.Ngamandla afanayo, uma intambo yeluliwe isikhathi eside, i-ductility iphakama.Ukuphakama kwe-ductility, kukhulu ukunwebeka kwentambo.Ngokwemigomo ye-layman, izintambo ezinwebeka kakhulu zibizwa ngokuthi "izintambo zamandla".I-elasticity encane, cishe engashintshi ngaphansi kwesenzo samandla angaphandle, okubizwa ngokuthi "intambo emile".Ngakho iyiphi engcono kulezi zintambo ezimbili?
Awukho umehluko ophelele phakathi kwezintambo eziguquguqukayo nezintambo ezimile, ngoba zisebenza ezindaweni ezihlukene.Inhloso yezintambo eziguquguqukayo ukumunca iningi lamandla ngentambo ngaphansi kwamandla aphezulu, futhi badlale indima ephelele.Umthelela omuhle kakhulu wokugoba, njengentambo esetshenziswa ku-bungee jumping, intambo yamandla yale njongo.
Intambo emile iwukugcina ubude obufanayo ngangokunokwenzeka ngaphansi kwesenzo samandla angaphandle, futhi le nzuzo yentambo emile ibonakala ngokusobala ekusebenzeni kokuphakamisa.Ngokunwebeka okuphansi kwentambo, umsebenzi wokuphakamisa uqinisekisiwe.Kwenze ngokuphepha.
Ngakho nansi inkinga iza.Njengamanje, iningi lezibambisi zokuwa ezisezingeni eliphezulu zisebenzisa indlela yokuxhuma intambo yocingo.Kumelwe wazi ukuthi intambo yocingo ayinakho ukunwebeka, okusho ukuthi uma kwenzeka ukuwa okuphezulu, intambo yocingo ayinayo indlela yokumunca noma yiliphi ikhono, kanye nomthelela Amandla azoxhunywa emzimbeni womuntu cishe anganqamuki.Kodwa iziboshwa eziningi eziwayo zisasebenzisa izintambo zocingo.Kungani?
Eqinisweni, le nkinga kulula ukuyiqonda, ngoba isibambisi sokuwa sihlukile ku-bungee jumping.Idizayini yesibambi sokuwa esisezingeni eliphezulu inembe kakhulu.Ngesikhathi sokuwa, i-ratchet kanye ne-pawl ingaqedela ukuzivala ngaphakathi kwemizuzwana engu-0.2, ngaleyo ndlela iqinisekise ukuthi ukukhiqizwa okuncane engozini enkulu yokuphepha.
Ngakho-ke, isibambisi sokuwa esisezingeni eliphezulu sisebenzisa izintambo eziningi “zezintambo ezimile”.kunokuba "intambo yamandla"
