Four forces act on a small airplane in flight, its weight (W)=25kn, lift provided by wings is (L)=25kn, the thrust provided by engine is (T)=10kn and the drag resulting from its motion through the air is (D)=3Kn. Determine the resultant of the four forces and its line of action with respect to the axis of plane.
