Imbali
Igama lesiNgesi elihambelana ne-screw yi-Screw.Intsingiselo yeli gama itshintshe kakhulu kumakhulu eminyaka yakutshanje.Ubuncinci ngo-1725, lithetha "ukukhwelana".
Ukusetyenziswa komgaqo womsonto kunokulandwa umva kwisixhobo sokuphakamisa amanzi esijikelezayo esenziwe ngumphengululi ongumGrike uArchimedes ngowama-220 BC.
Ngenkulungwane yesi-4 ye-AD, amazwe agudle ulwandle lweMeditera aqala ukusebenzisa umgaqo weebholiti kunye namandongomane koomatshini bokushicilela abasetyenziselwa ukwenza iwayini.Ngelo xesha, imisonto yangaphandle yayisongelwe yonke ngentambo kwi-cylindrical bar, ize ikrolwe ngokwalo phawu, ngoxa imisonto yangaphakathi yayidla ngokuyilwa ngokubethelela imisonto yangaphandle ngezinto ezithambileyo.
Malunga ne-1500, kumzobo wesixhobo sokulungisa intambo esizotywe ngu-Leonardo da Vinci wase-Italiya, kwakusele kukho umbono wokusebenzisa isikrufu sowasetyhini kunye negiya yokutshintshiselana ukwenza imisonto yeepitshi ezahlukeneyo.Ukususela ngoko, indlela yokusika imisonto ngoomatshini iye yaphuhliswa kwishishini laseYurophu lokwenza iiwotshi.
Ngowe-1760, abazalwana baseBritani uJ. Wyatt noW. Wyatt bafumana ilungelo elilodwa lomenzi wechiza lokusika izikrufu zomthi ngesixhobo esikhethekileyo.Ngomnyaka we-1778, iBritish J. Ramsden yakha yenza isixhobo sokusika intambo esiqhutywa yigeya yeentshulube, esinokuthi siqhube imisonto emide ngokuchaneka okuphezulu.Ngo-1797, iBritish H. Mozley yasebenzisa isikrufu sokukhokela esibhinqileyo kunye negiya yokutshintshiselana ukujika imisonto yentsimbi enemitsi eyahlukeneyo kwilathe ephuculwe nguye, kwaye yaseka indlela esisiseko yokujika imisonto.
Ngeminyaka yoo-1820, uMaudsley wenza ibhetshi yokuqala yeetephu kwaye wafela ukusetyenzwa komsonto.
Ekuqaleni kwenkulungwane yama-20, uphuhliso lweshishini leemoto lwakhuthaza ngakumbi ukubekwa emgangathweni kwemisonto kunye nophuhliso lweendlela ezahlukeneyo zokuchaneka kunye neendlela ezisebenzayo zokulungisa imisonto.Iintloko ezahlukeneyo zokuvula ezizenzekelayo zokuvula kunye neetephu ezizenzekelayo ezicuthekayo zayilwa enye emva kwenye, kwaye kwaqala ukusetyenziswa imisonto yokusila.
Ekuqaleni kweminyaka yee-1930, kwavela ukucola intambo.
Nangona iteknoloji yokuqengqa intambo yayinelungelo elilodwa lomenzi ekuqaleni kwenkulungwane ye-19, ngenxa yobunzima bokwenziwa kokungunda, uphuhliso lwalucotha kakhulu.Kwakungekho kwaze kwaba yiMfazwe Yehlabathi yesiBini (1942-1945) ukuba ngenxa yeemfuno zemveliso yezixhobo kunye nophuhliso lweteknoloji yokugaya intambo, ingxaki yasonjululwa.Ingxaki echanekileyo yokwenziwa komngundo iphumelele uphuhliso olukhawulezayo.
