Leta 1502 je sultan Bajazid II na\u010drtoval most \u010dez zaliv Zlatni rog, da bi povezal Istanbul in sosednje mesto Galata. Med odzivi vodilnih in\u017eenirjev tistega \u010dasa se je po svoji izvirnosti izstopal projekt znanega italijanskega umetnika in znanstvenika Leonarda da Vincija. Tradicionalni mostovi so bili takrat obi\u010dajno vidni z ukrivljeno lokom in ve\u010d pre\u010dkami. Za most nad zalivom bi potrebovali vsaj 10 podpore, vendar je Leonardo zasnoval most dol\u017eine 280 metrov brez edinega stebra. Projekt italijanskega u\u010dnega ni bil sprejet. Teh \u010dudes ne moremo videti. Je ta projekt deloval? Na to so odgovorili in\u017eenirji MIT, ki so po Leonardovih skicah zgradili<\/a><\/noindex> maketo mostu v razmerju 1:500 in jo preizkusili z vsemi mo\u017enimi obremenitvami.<\/p>\n

\"Engineers<\/p>\n

V resnici bi most sestavljala tiso\u010d stvarjenih kamnov. Na voljo ni bilo drugega primernega materiala (znanstveniki so se trudili \u010dim bolj pribli\u017eati gradbenim tehnologijam tistega \u010dasa in razpolo\u017eljivim materialom). Za izdelavo makete mostu so sodobni strokovnjaki uporabili 3D-tiskalnik in model razdelili na 126 blokov dolo\u010denih oblik. Kamni so bili zaporedno name\u0161\u010deni na gradbene odri. Po namestitvi vrhnjega kamna mostu so bili odri odstranjeni. Most je ostal pokon\u010den in bi zagotovo zdr\u017eal stoletja. Italijanski u\u010denjak renesanse je upo\u0161tevajo vse: od seizmi\u010dne nestabilnosti regije do stranskih obremenitev mostu.<\/p>\n

Izbrana Leonardova oblika splo\u0161\u010dene arkade je omogo\u010dila navigacijo po zalivu tudi jadrnicam z dvignjenimi jambori, medtem ko je zasnova, ki se \u0161iri proti dnu, zagotavljala stabilnost proti stranskim obremenitvam in, kot so pokazali poskusi z maketo, seizmi\u010dno stabilnost. Premi\u010dne platforme v dnu arkade so se lahko premikale v \u0161irokem razponu brez ru\u0161enja celotne konstrukcije. Gravitacija in nobenega pritrjevanja s pomo\u010djo malte ali pritrdilnih elementov \u2013 Leonardo je vedel, kar je predlagal.<\/p>\n
