N’chifukwa chiyani anthu omangira kugwa pamalo okwera kwambiri amagwiritsa ntchito zingwe zokhazikika m’malo mogwiritsa ntchito zingwe zolimba?

Ponena za chingwe, ponena za ductility yake, makamaka imagawidwa mu mitundu iwiri, imodzi ndi chingwe chokhazikika, china ndi chingwe chokhazikika.Anthu ambiri samamvetsetsa tanthauzo lenileni la chingwe champhamvu ndi chingwe chokhazikika, kotero Chenghua amachipanga molingana ndi kutalika kwake.Chingwe chachitetezo cha womangidwayo chidzakupatsani sayansi yodziwika bwino ya zingwe zokhazikika komanso zingwe zolimba.
Ductility akhoza kumvetsetsa ndi anthu ambiri, ndiko kuti, chingwe chikhoza kutambasulidwa pansi pa mphamvu yakunja.Kwa mphamvu yomweyo, chingwe chitalikirapo, ndiye kuti ductility imakwera.Kukwera kwa ductility, kukulirakulira kwa chingwe.M'mawu a layman, zingwe zotanuka kwambiri zimatchedwa "zingwe zamphamvu".Zing'onozing'ono za elasticity, pafupifupi zosasinthika pansi pa mphamvu ya kunja, yomwe imatchedwa "static chingwe".Ndiye ndi zingwe ziwiri ziti zomwe zili bwino?
Palibe kusiyana kwakukulu pakati pa zingwe zosinthika ndi zingwe zokhazikika, chifukwa zimagwira ntchito mosiyanasiyana.Cholinga cha zingwe zosunthika ndikuyamwa mphamvu zambiri kudzera mu chingwecho ndi mphamvu yamphamvu kwambiri, ndikuchita gawo limodzi.Njira yabwino kwambiri yopumira, monga chingwe chomwe chimagwiritsidwa ntchito polumphira bungee, ndi chingwe champhamvu cha izi.
Chingwe chosasunthika ndicho kusunga utali wofanana momwe kungathekere pansi pa mphamvu yakunja, ndipo ubwino wa chingwe chokhazikika umawonekera bwino mu ntchito yokweza.Kupyolera mu kutsika kochepa kwa chingwe, ntchito yokweza imatsimikiziridwa.Chitani mosatekeseka.
Ndiye pakubwera vuto.Pakali pano, ambiri mwa omanga kugwa kwapamwamba kwambiri amagwiritsa ntchito njira yolumikizira chingwe cha waya.Muyenera kudziwa kuti chingwe cha waya chilibe elasticity, zomwe zikutanthauza kuti pamene kugwa kwapamwamba kwambiri, chingwe cha waya sichikhala ndi njira yothetsera luso lililonse, ndipo zotsatira zake Mphamvuyo idzamangiriridwa ku thupi la munthu pafupifupi mosalekeza.Koma ambiri omanga kugwa amagwiritsabe ntchito zingwe zamawaya.Chifukwa chiyani?
M'malo mwake, vutoli ndi losavuta kumva, chifukwa chomangirira kugwa ndi chosiyana ndi kulumpha kwa bungee.Mapangidwe a high-atitude fall arrester ndi olondola kwambiri.Panthawi yakugwa, ratchet ndi pawl amatha kumaliza kudzitsekera mkati mwa masekondi a 0.2, potero kuonetsetsa kuti kupanga kakang'ono Kamodzi kamene kamamangidwa kamene kamakhala ndi chingwe cholimba kwambiri, sichingalepheretse kugwa kuti zisachitike mkati mwa masekondi 0.2, zomwe zimabweretsa. pachiwopsezo chachikulu chachitetezo.
Choncho, chomangirira kugwa kwapamwamba kwambiri chimagwiritsa ntchito zingwe za waya za "static".osati "chingwe champhamvu"
