Answer
Umubare ntarengwa wa fibre $ \ sigma $ kurwego rwo hejuru rwakazi ubaho hejuru yumuraba kandi ubarwa ukoresheje $ \ sigma = \ frac {3 \ pi P D_m} {4 b t ^ 2 N_w ^ 2} $, aho $ P $ ni umutwaro kuri ubwo burebure. Ikwirakwizwa ryimyitwarire ntirisanzwe kuko umurongo wamazi ukora nkurukurikirane rwibiti bigoramye; umwanya wo kugunama ni muremure aho uhurira (crests) kandi ugabanuka werekeza. Kubikoresho nka Inconel X-750, injeniyeri agomba kwemeza ko iyi mihangayiko ibarwa itarenze imbaraga nkeya yumusaruro wibikoresho mubushyuhe bwo gukora. Niba imihangayiko irenze hafi 80 ku ijana byimbaraga zumusaruro, isoko ishobora guhura nigihe cyose (deformasique ya plastike), ikunze kugereranywa hifashishijwe ibintu byakosowe kugirango amasoko menshi ahindurwe kugirango ubare geometrie nyayo hamwe no guterana amagambo hagati.
