, List five stresses imposed on an aircraft structure - ✔✔Compression- The stress that
tends to crush or press together
Tension- The stress in a member when a force tends to elongate and stretch it
Torsion- The stress of twisting
Bending- It is the combination of compression and tension
Shear- The stress developed when a force tend to cause a layer of material to slide along
an adjacent layer
Strain- The effect of overstressing a part or assembly to the point where a permanent
deformation takes place
Compare tension and torsion - ✔✔Tension is the stress of stretching an object while
torsion is the stress of twisting an object
Explain the purpose of station numbers for an airplane - ✔✔It is necessary to establish a
method of locating components and reference points on the aircraft.
List four types of station numbers - ✔✔Fuselage stations, wing stations, water line, butt
line and component stations.
Where is the butt line of an aircraft? - ✔✔It is the center line of the fuselage.
