The drawing shows a rectangular piece of wood. The forces appliedto corners B and D have the same magnitude of 11 N and are directedparallel to the long and short sides of the rectangle. The longside of the rectangle is twice as long as the short side. An axisof rotation is shown perpendicular to the plane of the rectangle atits center. A third force (not shown in the drawing) is applied tocorner A, directed along the short side of the rectangle (eithertoward B or away from B), such that the piece of wood is atequilibrium. Find the magnitude and direction of the force appliedto corner A.
