[填空题]
A potter is shaping a bowl on a potter’s wheel r8lry06k5o(qcw me c-a 7,nphgx9fa dxu+5l9 motating at constant angular speed (Fig. 8–42x +m9ax f95lud). The friction force between her hands and the clay is 1.5 N total. (a) How large is her torque on the wheel, if the diameter of the bowl is 12 cm? $m \cdot N$ (b) How long would it take for the potter’s wheel to stop if the only torque acting on it is due to the potter’s hand? The initial angular velocity of the wheel is 1.6 rev/s, and the moment of inertia of the wheel and the bowl is 0.11 $kg \cdot m^2$. s
