Three cases involving identical forces acting on identical sticks are shown in the figure. Compare the magnitudes of the torques about an axis through the center of the sticks. Torque(A) = Torque(B) > Torque(C) Torque(A) > Torque(B) > Torque(C) Torque(A) > Torque(B) = Torque(C) Case A Case B 30° Case C 30°
