The free body diagram below represents a 1 500 kg car sitting on a 3 000 kg bridge supported at its far ends. The car's position is three quarters of the length L from the left end of the bridge. Identify the one error in the torque equation below:

    



◦
never produces a torque on the bridge no matter where the axis of rotation is placed.

◦
never produces a torque on the bridge no matter where the axis of rotation is placed.

◦
cannot produce a torque on the bridge no matter where the axis of rotation is taken since it is at the center of the bridge.

◦
Because the perpendicular distance to from the left end of the bridge is 0, F1L should be 0.

◦
Because the perpendicular distance to from the right end of the bridge is 0, F2L should be 0.
