is this correct or are there other places where flexing would be a factor, ie. rudder, stabilizer, motor mount?
The doubler / bulkhead in which the leading edges of the tail feathers bolt into, comes to mind. Considering I had to replace this unit in 72G. But the stresses here usually are created from ground handling the aircraft by pushing and pulling on the tail feathers. Not by stresses of flight.
The Cessna landing gear is almost bullet proof. Many of my landings have gone to proving that point!
And I would think engine mount stresses would be taken up in the rubber mounts themselves on the most part.
I just cannot think of too many places that give and flex a whole bunch in the Cessna 150. One's first experience with turbulence usually is enough to convince most people of this fact! (Note: Do not wear base ball caps with the button on top while flying the 150/152 in rough air!)
