SUMMARY
The discussion focuses on ranking the torque magnitudes of six forces applied to a door, with forces of either F or 2F. The calculated torques are τ1 = F*L/2, τ2 = 2F*L/4, τ3 = F/√2*L/2, τ4 = F/√2*L/2, τ5 = 2F*L, and τ6 = 0. The correct ranking from smallest to largest is τ6, τ3 = τ4, τ2, τ1, τ5. The confusion arises from misinterpreting the relationship between the force magnitudes and their respective distances from the hinge.
