A square frame ABCD has a cut in the middle of side AD (see figure). Each side of the square has length L. and each member has flexural rigidity EI and torsional rigidity Glp . Equaland opposite forces P, with their lines of action perpendicular to the plane of the frame, are applied at the cut ends of the frame. Determine the gap between the cut ends (in the direction perpendicular to the plane of the frame).
