a) Fuselage, wing(s), stabilishing surfaces, landing gear and flying control surfaces.

b) Fuselage, wing(s), cockpit and flying control surfaces.

c) Wing(s), stabilishing surfaces, engine(s) and flying control surfaces.

d) Compressor, turbines, nozzle and combustion chamber.

With aircraft made up of mainly one wing, materials that were used were strong enough to bear the lift charge.

With aircraft made up of two wings in order to distribute the lift charge, inasmuch as materials that were used were not strong enough to bear the charge in only one wing.

By using semi-monocoque structures.

None of the above

a) Frames, longerons, stringers and formers

b) Frames, longerons and ribs

c) Skin, floor, squares and panels

d) All of the above

a) Frames make stronger the fuselage and spread the load

b) Longerons give longitudinal strength to the wing

c) Formers normally reinforce the shell structure when needed

d) All of the above are correct

a) Ground and inertial loads

b) Lift and drag

c) Ground and air loads.

d) Air and gusts loads.

a) Aerodynamic forces, acceleration, pressurization and weight.

b) Aerodynamic forces, acceleration, inertia and gusts.

c) Acceleration, inertia, weight and taxiing.

d) Aerodynamic forces, acceleration, inertia and pressurization.

a) The ratio between lift and weight of the aircraft.

b) Lower in turnings.

c) The ratio between weight of the aircraft and lift.

d) The ratio between lift and weight of the wings.

a) DLL is the load for structural failure.

b) Safety factor is 1.5 for aviation.

c) DLL= Safety factor x DUL

d) All are wrong.

a) Safety factor is greatest in construction.

b) Safety factor is 1.5 for aviation.

c) Greater safety factor implies less weight.
