Answer
Ƙunƙwasawa na gefe yana faruwa lokacin da tsayin kyauta na Crest-to-Crest ya fi girma fiye da ma'anarsa $D_m$ (yawanci $L_0/D_m> 4$). Ƙarƙashin kaya, ruwan bazara yana aiki kamar ginshiƙi siririn kuma yana ruku'u a waje. Wannan yana haifar da ɗaukar nauyin da ba axial ba, rarraba damuwa mara daidaituwa, da yuwuwar hulɗa tare da ganuwar gidaje, wanda ke ƙara haɓakawa da lalacewa. Maganin ya ƙunshi amfani da sandar jagora na ciki ko hannun riga na waje don ba da tallafi na gefe. A ilimin lissafi, ana iya ƙididdige nauyin nauyi mai mahimmanci $P_{cr}$ ta amfani da gyare-gyaren Euler's formula $P_{cr} = \ frac{\pi^2 \cdot E \cdot I_{eff}}{(K \cdot L)^2}$, inda $I_{eff}$ shine ingantaccen lokacin inertia na tsarin igiyar ruwa.
