Answer
Fadada radial $ \ Delta r$ na zoben riƙewa saboda juyawa ana ba da shi ta $\Delta r = \ frac{\rho \cdot \ omega^2 \cdot R^3}{E}$, inda $\rho $ shine yawa, $\omega $ shine saurin angular, kuma $ R$ shine ma'anar radius. Zoben zai gaza lokacin da $\Delta r$ ya wuce zurfin tsagi $d$. Musamman ma, ana ƙididdige madaidaicin saurin $N$ (a cikin RPM) azaman $N = \sqrt{\frac{440 \ times 10^6 \cdot E \cdot I}{w \cdot \rho \cdot R^4}}$, ana zaton an yi zoben da karfe. Idan aikace-aikacen yana buƙatar gudu sama da wannan iyaka, dole ne a yi amfani da zoben 'Kulle Kai' ko zoben ɓangaren giciye mafi nauyi. Bugu da ƙari, dacewa dole ne ya zama m; zoben sako-sako da zai fara faɗaɗa a ƙaramin RPM fiye da zobe mai babban 'ƙuƙwalwa' (tsangwama).
