Umzobo weenkcukacha

Yintoni "UN" Umsonto?

Inkangeleko yomsonto weSizwe waseMelika (i-angle ye-60 yeprofayili kunye ne-H / 8 flatness) yahlukile kwiprofayili ye-Wyeth (i-angle ye-55 yeprofayili kunye ne-H / 6 ukuphakama). I-American National Thread isetyenziswa ngokubanzi kwimimandla kunye namashishini aphenjelelwa lishishini laseMelika. KwiMfazwe Yehlabathi yesiBini, ngenxa yemigangatho engahambelaniyo yentambo esetyenziswa yi-Allies, ubunzima bokubonelela ngempahla bubangele ilahleko enkulu yezoqoqosho kunye nokulimala kwi-Allies. Ngokukhawuleza emva kokuphela kweMfazwe Yehlabathi II, i-United States, i-United Kingdom, iKhanada kunye namanye amahlakani aqala ngokukhawuleza ukwenza umgangatho odibeneyo phakathi kwamazwe ahlangeneyo, kwaye abhengeza umgangatho odibeneyo wentambo ngo-1948.

Ngenxa yokuba amandla ezoqoqosho kunye namandla omkhosi wase-United States ayelawula imikhosi eManyeneyo ngelo xesha, intambo edibeneyo yayiyilwe ngokukodwa ngokwemigangatho yesizwe yase-United States. Umanyano "; unobumba wokugqibela "N" uthatyathwe kwigama elithi "N" lemisonto yeSizwe yaseMelika. Ukususela ngoko, intambo edibeneyo yaqala ukucudisa imarike yokusetyenziswa yasekuqaleni kwentambo yaseBritish Whitworth.
