Question
Where does material selection start?
Answer
At the requirement, not the material. Each requirement names a property with a number, which a candidate either meets or does not.
Question
How are essential properties used in selection?
Answer
As a filter: a candidate failing one is out however well it scores elsewhere. Mass, cost, availability and aesthetics then rank whatever survives.
Question
Strength or stiffness — which fixes a flexing seat?
Answer
Stiffness. Strength is the load before it breaks; stiffness is how little it bends before then. Section depth and shape affect stiffness at least as much as the material does.
Question
What must an answer contain beyond the material name?
Answer
The requirement, the property it demands, and the consequence for the user. A material name on its own earns nothing.
