Ngowe-1950, isazi ngefiziksi uGeorge Gamow noMarvin Stern baphawula into ebangel’ umdla: UGamow, owayeneofisi kumgangatho wokuqala wesakhiwo esinemigangatho emithandathu, waphawula ukuba ilifti elandelayo ihla kangangezihlandlo ezihlanu kwezintandathu, nangona wayefuna. ukunyuka. UStern, owayesebenza kumgangatho wesihlanu, waphawula okwahlukileyo koko.
I-elevator yayidla ngokuvela kumgangatho ophezulu kwaye ihle xa ifuna ukuhla. Kwisakhiwo esinemigangatho emininzi, ilifti elandelayo efikayo kaninzi ibonakala isiya kwelinye icala kunokuba ulindele. Inkcazo yesiganeko ilele kwixesha elahlukileyo elichithwa yi-elevators kwimigangatho eyahlukeneyo.
Kwimigangatho ephantsi, i-elevator elandelayo ihla rhoqo ngenxa yokuba ixesha lokuhamba phantsi lifutshane kunexesha lokunyuka. Kwimigangatho ephezulu imeko iguqulwa: Apha amathuba okuba i-elevator elandelayo iya kunyuka iphezulu kuba ixesha lokuhamba phantsi kunye nokubuya lide.
Ukuba ukumgangatho ophezulu wesakhiwo, zonke izinyusi ziphuma ngaphantsi (akukho nanye enokuvela phezulu) zize zihle, ngelixa ukuba ukwinqanaba lesibini ukuya kumgangatho wokugqibela, okokuqala ilifti inyuke iye kumgangatho ongaphezulu ize emva koko iphume. yehla kamsinya emva kokudlula - ngelixa inani elilinganayo lezinyusi lidlula phezulu ukuya ezantsi, izinyusi ukuya ezantsi ngokuqhelekileyo zilandela izinyusi phezulu ngokukhawuleza, kwaye ke ilifti yokuqala ejongweyo idla ngokuhambela phezulu.
I-elevator yokuqala ejongwayo iyehla kuphela xa umntu eqala ukujonga ngexesha elifutshane emva kokuba i-elevator ephezulu idlula, ngelixa ixesha eliseleyo i-elevator yokuqala ejongwayo inyuka.
I-elevator enye ichitha ixesha layo elininzi kwindawo enkulu yesakhiwo kwaye ke ngoko kunokwenzeka ukuba ivela kwelo cala xa umsebenzisi onokubakho we-elevator efika. Umntu obukeleyo owayehleli kwiingcango zeelevator kangangeeyure okanye iintsuku, ebukele ilifti nganye ifika, kunokuba abukele nje ilifti yokuqala , uya kuphawula ukuba kukho inani elilinganayo lezinyusi eziya kwicala ngalinye.
Sazi njani ukuba kukho inani elifanayo lezinyusi kwicala ngalinye? Oku kwenziwa ngokugcina izinyusi . Ukuba, kwinqanaba elithile, kukho izinyusi ezininzi ezinyukayo kunokuhla, inani lezinyusi liya kuncipha ngokuthe ngcembe ngaphantsi kwelo nqanaba, into engenakwenzeka.
