The figure shows forces acting on a meter stick, which is constrained to rotate around the axis indicated by the dot $\bullet$Which force(s) create a positive torque around that axis?

Question

Quizplus · Accepted Answer

The forces that create a positive torque around the indicated axis are those that produce a counterclockwise rotation. Looking at the figure, we can see that only force B has a component that points counterclockwise and is not exactly balanced by the other forces. Therefore, force B is the only one that creates a positive torque around the indicated axis.
