Three equal forces applied to a rectangle, find net torque direction?

SUMMARY
The discussion focuses on calculating net torque and its direction for three forces acting on a rectangle. The participants clarify that the net torque about point A is zero due to equal and opposite forces F1 and F2, while F3 does not contribute to torque as it acts through the center of mass. At point B, the net torque is counterclockwise due to F1 and F2, and at point C, the net torque is also zero. The importance of calculating the lever arms for each force to determine the net torque is emphasized throughout the conversation.
