A pair of forces with equal magnitudes, opposite directions, and different line 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 shoes a couple acting on a tire wrench, each force being perpendicular to the wrench. Let L=0.438 m and F =20.6 N. Determine the torque produced by the couple when the axis is perpendiular to the tire and passe through (a) point A, (b) point B, (c) point C
The net torque will be zero under the equilibrium condition
Apply this condition at each of the points.
At point A,
At point ...
