Answer
Matsakaicin ka'idar bazara $k$ don maɓuɓɓugan ruwan Crest-zuwa-Crest da yawa tare da ƙarshen shim an samo shi daga dabarar: $k = \ frac {E \ cdot b \cdot t ^ 3 \ cdot N^4}{D_m^3 \ cdot Z \ cdot 583}$, inda $E $ shine Modulus $ Ela, Maɓallin $ Ela shine Maɓallin $ Ela. kauri, $N$ shine adadin raƙuman ruwa a kowane juyi, $D_m$ shine matsakaicin diamita, kuma $Z$ shine adadin juyawa mai aiki. A aikace, lanƙwan jujjuyawar lodi ya kasance madaidaiciya tsakanin 20% zuwa 80% na jujjuyawar da ake samu. Yayin da bazara ke gabatowa 'tsawo mai ƙarfi', tãguwar ruwa suna fara 'wuri' ko taɓawa, wanda zai rage girman tsayin katako kuma yana ƙara adadin raƙuman ruwa $ N$ suna aiki a layi daya. Wannan yana haifar da haɓaka mai ƙima a cikin ƙimar bazara, galibi ana bayyana shi azaman $k_{ainihin} = k_{theoretical} \cdot (1 - \ frac{f}{h})^{-1}$ inda $f$ ke karkata kuma $h$ shine tsayin kyauta, kodayake ana buƙatar gwaji mai ƙarfi don daidaitaccen ƙirar ƙirar tsayin tsayi.
