Answer
Rayuwar gajiyawar magudanar ruwa tana da alaƙa da alaƙa da kewayon damuwa $\Delta \ sigma$ da aka samu yayin hawan keke. Tun da $\ sigma \propto D_m / (b t^2 N_w^2)$, matsakaicin diamita yana taka muhimmiyar rawa. Ƙara $D_m$ don ƙayyadadden kaya $P$ a zahiri yana ƙara lokacin lanƙwasawa da sakamakon damuwa. Yin amfani da dangantakar Goodman, $\frac{\sigma_a}{S_e} + \ frac{\sigma_m}{S_u} = 1 $ (inda $ \ sigma_a $ shine madaidaicin danniya, $ \ sigma_m $ yana nufin damuwa, $ S_e $ shine iyakacin juriya, kuma $ S_u $ shine iyakar ƙarfin ƙarfin ƙarfi), injiniyoyi dole ne su inganta ƙarfin ƙarfi. A cikin bawuloli na cikin teku inda dogara na dogon lokaci ya zama mafi mahimmanci, yawancin raƙuman ruwa $ N_w $ galibi ana fifita su fiye da $ D_m$ mafi girma don rage damuwa a kowace igiyar ruwa kuma ƙara rayuwar sake zagayowar zuwa cikin $10^6$.
