Answer
Uburebure bukomeye $ H_s $ yumuraba wuburebure nuburebure bwa axial mugihe isoko yamenetse kuburyo imiraba yose iba ihuye. Kuri Crest-to-Crest isoko, $ H_s = N \ cdot t $, aho $ N $ numubare wimpinduka naho $ t $ nubunini bwibintu. Ariko, kubisoko bifite shim birangira, formula iba $ H_s = (N + 2) \ cdot t $. Mugihe amasoko yegereje $ H_s $, umutwaro-gutandukanya umurongo uhinduka utari umurongo, werekana ubwiyongere bukabije bwimbaraga mugihe aho uhurira uva mumasonga yumuraba ukagera hejuru. Gukoresha isoko hafi ya $ H_s $ biracika intege kubera ko 'guhangayika gukomeye' akenshi birenze urugero rwibintu byoroshye, biganisha kumurongo uhoraho. Abashushanya bakoresha ibintu byumutekano $ \ eta = \ sigma_ {umusaruro} / \ sigma_ {ikomeye} $ kandi mubisanzwe bagabanya gutandukana kwakazi kugeza $ 80 \% $ byurugendo rushoboka kuri $ H_s $ kugirango bakomeze imyitwarire iteganijwe.
