A pair of forces with equal magnitudes, opposite directions, and different lines of action is called a "couple." When a couple acts on a rigid object, the couple produces a torque that does not depend on the location of the axis. The figure shows a couple acting on a tire wrench, each force being perpendicular to the wrench. Let L = 0.281 m and F= 28.2 N. Determine the torque produced by the couple when the axis is perpendicular to the tire and passes through (a) point A, (b) point B, and (c) point C.

Assume a single 300-N force is exerted on a bicycle frame as shown in Figure OQ10.5. Consider the torque produced by this force about axes perpendicular to the plane of the paper and through each of the points A through E, where E is the center of mass of the frame. Rank the torques A, B, C, D, and E from largest to smallest, noting that zero is greater than a negative quantity. If two torques are equal, note their equality in your ranking. Figure OQ10.5
