Answer
Uburebure bukomeye ni ingingo aho imiraba yose yegeranye. Gucomeka isoko yumurambararo kugeza murwego rukomeye akenshi birenze urugero rwibintu byoroshye, cyane cyane mubishushanyo biremereye. Ibisubizo muri 'gushiraho', aho uburebure bwubusa $ H_ {ubuntu} $ bugabanuka. Guhangayikishwa n'uburebure bukomeye $ \ sigma_s = \ frac {3 π E t (H_ {ubuntu} -t_ {ikomeye})} {4 N ^ 2 D_m ^ 2} $ bigomba kugereranywa nimbaraga zitanga umusaruro. Niba $ \ sigma_s> \ sigma_y $, isoko ntizasubira muburebure bwambere. Mubikorwa bimwe na bimwe byo gukora, 'presetting' birakorwa: isoko yisunitswe nkana kugeza murwego rwo hejuru kugirango 'ikureho' ibice byambere kandi ihagarike umutwaro. Niba isoko mu murima isanze ifite uburebure bwubusa, ni ikimenyetso cyerekana ko inteko yageze kumiterere 'hasi-hanze' mugihe ikora.
