Question

The drawing shows a rectangular peice of wood. The forces applied to corners B and D have the same magnitude of 14 N and are directed parallel to the tlong and short sides of the rectangle. The long side of the rectangle is twice as long as the short side. An axis of rotation is shown perpendicular to the place of the rectangle at its center. A third force (not shown in the drawing) is applied to corner A, directed along the short side of the rectangle (either toward B or away from B), such that the piece of wood is at equillibrium. Find the magnitude and direction of the force applied to corner A.
