Igipimo cyimpeshyi $ k $ kubintu byinshi byahindutse Crest-to-Crest umuraba wamasoko ukomoka kubitekerezo bya beam bikoreshwa mubice bigoramye. Inzira isanzwe ni $ k = \ frac {E b t ^ 3 N ^ 4} {4 D_m ^ 3 n} $, aho $ E $ ari Modulus ya Elastique, $ b $ ni ubugari bwurukuta rwa radiyo, $ t $ nubunini bwibikoresho, $ N $ numubare wumuraba kumurongo, $ D_m $ numubare uhinduka, naho $ n $ numubare uhinduka. Muri iyi miterere, impinduka zikora nkamasoko murukurikirane, niyo mpamvu igipimo gihwanye na $ n $. Ba injeniyeri bagomba kwemeza ko gutandukana bitarenze umurongo, mubisanzwe bisobanurwa nka $ 80 \% $ byurugendo rushoboka kugirango birinde guterera umuraba cyangwa 'gusohoka' bitera igicucu kidafite umurongo.
