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. Determine the equivalent couple moments created about the x' and y' axis.

Mx' = 26.0 kip-ft, My' = 29.8 kip-ft
Mx' = 29.8 kip-ft, My' = -4.84 kip-ft
Mx' = 26.0 kip-ft, My' = 15.47 kip-ft
Mx' = 29.8 kip-ft, My' = 4.84 kip-ft

Mx'= 25sin25+17cos25 = 25.97kN.m.
My'= 25cos25-17sin25 = 15.47kN.m.
