Answer
Ubushobozi bwo gukata impeta $ F_r $ bugenwa na formula $ F_r = D t \ pi \ tau_ {ult} / K $, aho $ t $ nubunini bwimpeta, $ D $ ni diameter ya groove, naho $ \ tau_ {ult} $ nimbaraga zogosha zikoreshwa mubikoresho. Kubyuma byinshi byamasoko, $ \ tau_ {ult} \ hafi 0,6 \ cdot \ sigma_ {uts} $. Mubisabwa birimo inshuro nyinshi cyangwa ingaruka zumutwaro, ibintu byumutekano $ K $ bigomba kongerwa kugeza byibuze 3. Niba $ F_r $ ari munsi yumutwaro wa serivisi usabwa, uburebure bwimpeta bugomba kongerwa, cyangwa impeta ihinduranya byinshi igomba gutondekwa kugirango ikwirakwize inkweto ahantu hanini.
