A rigid uniform bar of length 2.4 m is pivoted horizontally at its midpoint. [Figure showing a pivoted bar with 200 N weight at 0.8 m left and 300 N weight at 0.8 m right from the pivot] Weights are hung from two points on the bar as shown in the diagram. To maintain equilibrium, a couple is applied to the bar. What is the torque and direction of this couple?
