Answer
Umubare wumuraba $ N $ ufite ingaruka zikomeye kumikorere yimpeshyi. Igipimo cyimpeshyi $ k $ gihwanye na $ N ^ 4 $ ($ k \ propto \ frac {E \ cdot b \ cdot t ^ 3 \ cdot N ^ 4} {D_m ^ 3} $). Ongeraho imiraba byongera cyane gukomera. Nyamara, uko $ N $ yiyongera, kwemererwa gutandukana $ f $ bigabanuka kubera ko intera yumubiri iri hagati yimisozi iba ntoya, biganisha ku mpagarike ihanamye kandi ihangayikishijwe cyane no gutandukana. Guhangayikishwa $ S $ bihwanye na $ 1 / N ^ 2 $. Kubwibyo, isoko ifite imiraba myinshi irashobora gutwara umutwaro urenze $ P $ ariko ku giciro cyo kugabanya ingendo. Ba injeniyeri bagomba kuringaniza $ N $ kugirango bagere ku mbaraga zisabwa $ P $ mu mwanya uhari wa axial utarenze imbaraga z’ibikoresho.
