Answer
Impeta ya spiral yashizwemo no kuyizunguza mu gikoni. Guhangayikishwa no kwaguka (ku mpeta zo hanze) cyangwa kugabanuka (ku mpeta y'imbere) bigomba kuguma munsi yumusaruro wibikoresho kugirango wirinde guhinduka burundu. Umubare munini wa fibre mugihe cyo kwishyiriraho ni $ \ sigma_ {inst} = \ frac {E imes t imes (D_g - D_f)} {D_g imes D_f} $, aho $ D_g $ ni diameter ya groove na $ D_f $ ni diameter yubusa. Niba $ \ sigma_ {inst}> S_y $, impeta ntizasubira muburyo bwayo bwambere, bivamo guhinduka. Kuri 302 Impeta zidafite ibyuma, impagarike ntarengwa yo kwaguka isanzwe igarukira kuri $ 1 \% $ kugeza $ 2 \% $ ya diameter kugirango ikomeze 'guswera'.
