Find the net torque on the wheel in the figure below about the axle through o perpendicular to the page, taking a = 9.00 cm and b = 27.0 cm. (indicate the direction with the sign of your answer. assume that the positive direction is counterclockwise.) n · m a wheel rotating about an axle is approximated as two concentric circles with the center defined to be o. the radius of the inner circle is a and the radius of the outer circle is b. three arrows representing individual forces are as follows. an arrow labeled 12.0 n acts on the top left of the inner circle, and points down and to the left at an angle of 30.0° below the horizontal. an arrow labeled 10.0 n acts on the top of the outer circle and points to the right. an arrow labeled 9.00 n acts on the right of the outer circle and points down.
