Q

(FAA Aircraft Structural Manual)

Five major stresses to which all aircraft are subjected to?

A
  1. Tension - stress that resists a force that tends to pull something apart.
  2. Compression - stress that resists a crushing force.
  3. Torsion - stress that produces twisting.
  4. Shear - stress that resists the force tending to cause one layer of a material to slide over an adjacent layer.
  5. Bending - stress combining compression and tension.
72
Q

(FAA Aircraft Structural Manual)

Ailerons function?

A

(TQ)Ailerons are the primary flight control surfaces that move the aircraft about the longitudinal axis. In other words, movement of the ailerons in flight causes the aircraft to roll.

(TQ) When the aileron on one wing deflects down, the aileron on the opposite wing deflects upward.
