Question
How are materials classified by source?
Answer
As natural (timbers, textiles, biomaterials) or human-made (metals, polymers, glass, composites, smart materials).
Question
What is a frame structure? Give two examples.
Answer
One that carries its loads through a skeleton of linear members, with the spaces between open or non-structural. A bicycle, a roof truss, a tent.
Question
What is a shell structure, and what is its advantage?
Answer
One where the outer skin itself carries the load, usually because it is curved. It encloses and protects while using very little material for the volume it contains.
Question
Why is 'combination' the right answer for most products?
Answer
Because real products use each structure where its advantage matters — a car has a frame chassis, shell body panels and solid brake discs.
