Airframe Structure

A Fuselage Station is a

• lateral line on an aircraft wing.
• vertical line on aircraft fuselage.
• longitudinal line on the aircraft fuselage.

The main forces on an aircraft structure are

• tension, compression, torsion, and shear.
• tension, compression, torsion and strain.
• tension, compression, twisting, and shear.

A member taking a compression load is called a

• beam.
• cable.
• fairing.

Which of the following is primary structure for fuselage?

• Frame.
• Rib
• Stringer.

Which parts of the aircraft are classified secondary structures?

• These parts of the airframe are highly stressed but if damaged will not cause failure of the aircraft.
• These parts of the airframe are highly stressed and if damaged may cause failure of the aircraft and loss of life.
• These are lightly stressed parts such as fairings, wheel shields and minor component brackets et

One purpose of a rib is to

• support the bending loads on a fuselage.
• form the main lateral member in an aerofoil.
• maintain the correct contour of aerofoils covering.

The two common configurations for landing gear arrangements are:

• Conventional and tricycle
• Traditional and bicycle
• Amphibian and belly gear

What is attached to the rear of the vertical stabilizer?

• Elevator.
• Aileron.
• Rudder.

An elevator controls the aircraft motion in

• yaw.
• pitch.
• roll.

Jet engines are usually mounted by

• aluminum castings.
• forged mounts and bolted to aircraft forged structure.
• welded steel tubing.
