Answer
Ƙwayoyin ɗorewa na waje suna ƙarƙashin rundunonin centrifugal waɗanda ke haɓaka zoben radially. A wani ƙayyadadden saurin jujjuyawa $\omega$, zoben zai rasa rikonsa a gindin tsagi, wanda aka sani da ɗagawa. Matsakaicin saurin $V$ (a cikin RPM) na iya kusanta ta $V = \sqrt{\frac{4.48 \ times 10^{12} E t p^2}{D_g^3 D_r \rho}}$, inda $E$ shine Modulus, $t$ shine kauri na abu, $p$ shine bangon radial kyauta, $D gr shine bangon radig. diamita, kuma $\rho$ shine yawa. Don hana ɗagawa a cikin manyan igiyoyi masu sauri (misali, turbochargers), injiniyoyi za su iya saka zoben 'Kulle Kai', waɗanda ke da tsarin tab-da-slot wanda ke hana zoben faɗaɗa sama da wani wuri, ƙyale taron ya yi aiki a mafi girman RPMs.
