Find the net torque on the wheel in the figure below about the axle through O perpendicular to the page, taking a = 5.00cm and b = 23.0 cm. (Indicate the direction with the sign of your answer. Assume that the positive direction iscounterclockwise.) N m A wheel rotating about an axle is approximated as two concentric circles with the center definedto be O. The radius of the inner circle is a and the radius of the outer circle is b. Three arrows representing individualforces 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 anangle 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. Anarrow labeled 9.00 N acts on the right of the outer circle and points down.
