Answer
Matsakaicin RPM na zobe na waje yana iyakance ta ƙarfin centrifugal, wanda ke sa zoben ya faɗaɗa radially. Gudun $N$ wanda zobe zai fara daga tsagi yana bayar da $N = _x000c_rac{1}{ ext{rad/sec hira}} imes _x000c_rac{1}{D_m} imes _x000c_rac{ext{Groove Depth}}{ ext{Expansion Constant}$. A bisa ƙa'ida, mahimmin saurin $V_c$ ana samunsa ta hanyar daidaita ƙarfin centrifugal $F_c = m imes _x000c_rac{v^2}{R}$ akan riko na ciki na zobe. Tsarin da injiniyoyi ke amfani da shi shine $V = _x000c_rac{1}{ ext{π} D_i} imes ext{sqrt} _x000c_rac{48 E I g riangle}{w _x000d_ho A R_m^4}$, inda $ riangle $ shine madaidaicin radial tsakanin zobe, $_d_0. $I$ shine lokacin rashin aiki. Sama da wannan gudun, zoben yana rasa 'manne' kuma ana iya fitar dashi.
