Ngokubhekiselele kwintambo, ngokumalunga ne-ductility yayo, ihlulwe kakhulu ibe ziindidi ezimbini, enye yintambo eguqukayo, enye yintambo emileyo.Abantu abaninzi abayiqondi intsingiselo yokwenyani yentambo eguquguqukayo kunye nentambo emileyo, ngoko ke iChenghua iyenza ngokwendawo ephezulu.Intambo yokhuseleko yombambisi wokuwa iya kukunika inzululwazi edumileyo malunga nentambo engashukumiyo kunye nentambo eguqukayo.
I-Ductility inokuqondwa ngabantu abaninzi, oko kukuthi, intambo inokolulwa phantsi kwesenzo samandla angaphandle.Kumandla afanayo, okukhona intambo isoluliwe, kokukhona i-ductility iphezulu.Iphezulu i-ductility, i-elasticity enkulu yentambo.Ngokwemigaqo ye-layman, ngakumbi iintambo ezinwebekayo zibizwa ngokuba “ziintambo zamandla”.I-elasticity encinci, iphantse ingatshintshi phantsi kwesenzo samandla angaphandle, okubizwa ngokuba "yintambo ye-static".Ke yeyiphi kwezi ntambo zimbini ilungileyo?
Akukho mahluko upheleleyo phakathi kweentambo eziguquguqukayo kunye neentambo ezimileyo, kuba zisebenza kwiimeko ezahlukeneyo.Injongo yeentambo eziguqukayo kukufunxa uninzi lwamandla ngentambo phantsi kwamandla empembelelo ephezulu, kwaye udlale indima epheleleyo.Eyona mpembelelo intle yokuthomalalisa, efana nentambo esetyenziswa ekuxhumeni i-bungee, yintambo yamandla yale njongo.
Intambo engashukumiyo kukugcina umphakamo ofanayo kangangoko kunokwenzeka phantsi kwentshukumo yamandla angaphandle, kwaye olu ncedo lwentambo engashukumiyo lubonakaliswa ngokucacileyo kumsebenzi wokuphakanyiswa.Ngokusebenzisa i-elasticity ephantsi yentambo, umsebenzi wokunyusa uqinisekisiwe.Kwenze ngokukhuselekileyo.
Ke nantsi ingxaki isiza.Okwangoku, uninzi lwababambeli abaphezulu bekwindla basebenzisa indlela yokudibanisa intambo yocingo.Umele ukwazi ukuba intambo yocingo ayinayo i-elasticity, oku kuthetha ukuba xa kwenzeka ukuwa okuphezulu, intambo yocingo ayinayo indlela yokufumana nayiphi na ikhono, kunye nefuthe I-force ifakwe kumzimba womntu phantse ingathinteli.Kodwa abaninzi ababambisi bewile basasebenzisa iintambo zocingo.Ngoba?
Enyanisweni, le ngxaki kulula ukuyiqonda, kuba i-wall arrester yahlukile kwi-bungee jumping.Uyilo lwe-high-altitude fall arrester luchaneke kakhulu.Ngethuba lokuwa, i-ratchet kunye ne-pawl inokugqiba ukuzitshixa ngaphakathi kwemizuzwana ye-0.2, ngaloo ndlela iqinisekisa ukuba ukuveliswa kwezinto ezincinci Emva kokuba i-wall arrester ithatha intambo ye-elastic engaphezulu, ayikwazi ukuthintela ukuhla ukuba kwenzeke ngaphakathi kwemizuzwana ye-0.2, okubangelwa kwingozi enkulu yokhuseleko.
Ngoko ke, isibambisi sokuwa esikwindawo ephakamileyo sisebenzisa iintambo zocingo "ze-static".kunokuba "intambo yamandla"
