The main beam along the wing of an airplane is swept back at an angle of 25°. From load calculations it is determined that the beam is subjected to couple moments aMx = 25,000 lb • ft and My = 17,000 lb • ft. D

The main beam along the wing of an airplane is swept back at an angle of 25°. From load calculations it is determined that the beam is subjected to couple moments aM_x = 25,000 lb • ft and M_y = 17,000 lb • ft. Determine the equivalent couple moments created about the x' and y' axis.
