In the figure below, a horizontal board is held against a vertical wall. A cable is affixed to the end of a 1.64 m board with tension 310 N and θ = 26.2 degrees. Determine the magnitude of the torque that the cable exerts on the board, using the point where the board contacts the wall as the pivot point.
