Answer
Adadin bazara $k$ na maɓuɓɓugar ruwan ruwan Crest-zuwa-Crest an samo shi daga nakasar katako mai lankwasa. Don bazara tare da jujjuyawar aiki $ N $ da $ Z$ taguwar ruwa a kowane juyi, ana siffanta ƙimar a matsayin $k = \ frac {E b t^3 Z^4}{1.5 \pi D_m^3 N} \frac{I_D}{O_D}$, inda $E $ shine Modulus na Ƙarfafawa, $ b$ shine bangon radial_ diamita, $t $ shine kauri na abu. Lokacin da aka ƙara ƙarshen shim, ƙimar juyi mai tasiri yana ƙaruwa kaɗan saboda shim yana aiki azaman iyaka mai ƙarfi, yana rage tsayin juyi mai aiki. Don aikace-aikacen madaidaicin madaidaicin, ma'aunin gyara don ma'anar diamita $D_m = (D_{outer} + D_{inner}) / 2$ dole ne a ba da lissafin fadada radial yayin matsawa, yayin da $D_m$ ya ƙaru kaɗan, mai yuwuwar haifar da sakamako mai ƙarfi mara layi yayin da bazara ke gabato da tsayin sa $H_s$.
