Structure Type that uses a specific shape, usually a box/cylinder.
Open truss
Structure Type with frame/equipment directly attached to structural elements.
Body mounted.
Structure Type using both Open Truss and Body Mounted.
Combination
Pull something apart (structure load).
Tension structure load
Opposing loads applied to perpendicular cross-sections (structure load).
Shear
Pushing something together (structure load).
Compression
Produced by twisting (structure load).
Torsion
Effects of a load applied to a structure.
Stress
Stress causes a temporary change in shape or deformation of structure. What is the amount of deformation per unit length?
Strain
What structure mechanisms can only be used a few times (e.g., deployment of solar arrays, antennas, and booms?).
Low Cycle Mechanisms
What structure mechanisms can be used constantly throughout vehicle life?
High Cycle Mechanisms
What structural space hazard involves internal heat generation and heat absorbed by the spacecraft?
Thermal Radiation
What structural space hazard results in cold welding and outgassing?
Space Vacuum
What structural space hazard results in collisions with natural debris?
Micrometeoroids/Space debris
What structural space hazard results in oxidized metals and eroded polymers?
Atomic oxygen
