Ta yaya ake ƙididdige mafi ƙarancin zurfin tsagi ($ d$) da ake buƙata don hana 'fitar da zobe' don nauyin axial da aka ba shi $P$?

Matsakaicin zurfin zurfin $d$ an ƙaddara ta hanyar buƙatun cewa kayan tsagi dole ne su goyi bayan nauyin axial ba tare da samun nasara ba. Tsarin shine $d = \ frac {P \ cdot K}{\pi \cdot D \cdot \sigma_y}$, inda $P$ shine kaya, $ K$ shine ma'aunin tsaro, $ D$ shine diamita, kuma $ \ sigma_y $ shine ƙarfin samar da kayan gida. Bugu da ƙari, $d$ dole ne ya yi zurfi sosai don tabbatar da cewa bangon radial na zoben $w$ ya nutse sosai. Dokokin aikin injiniya na gama gari shine cewa $d$ yakamata ya zama aƙalla $25\%$ zuwa $50\%$ na kaurin zoben $T$ don samar da kwanciyar hankali. Idan tsagi ya yi zurfi sosai, lokacin dafa abinci zai sa zoben ya gaza ta hanyar 'zamewa' a gefen tsagi maimakon yanke kayan zoben.
