Umxholo Wembali: Ukuguquka KwamaPlate Omphezulu
Ipleyiti yomphezulu ochanekileyo inembali etyebileyo eqala ekuqaleni kwenkulungwane ye-19. UHenry Maudslay, injineli yaseBritane eyayinguvulindlela, waqala ukuphuhlisa iindlela zokukrwela ngesandla ukuvelisa iipleyiti zesinyithi ezithe tyaba kakhulu, ezibonelela ngendawo ebalulekileyo yokulinganisa ngokuchanekileyo kunye nokulungisa. Kamva, uJoseph Whitworth waphucula waza wapapasha indlela yeepleyiti ezintathu ngo-1840, eseka iindlela zokuvelisa ezisemgangathweni ezazivumela ukuveliswa okuthembekileyo kweendawo ezitshintshanayo.
Kangangeminyaka ephantse ibe yi-150, isinyithi esityhidiweyo sasilawula imarike yeepleyiti eziphezulu. Nangona kunjalo, ngexesha leMfazwe Yehlabathi yesiBini, ukunqongophala kwesinyithi kwakhokelela ekuveliseni izinto ezintsha. UWallace Herman kunye noDonald V. Porter eMelika baqala ukuzama igranite njengenye into.
