Properties and materials testing

1. Properties that refer to actual matter that forms the material (8, 10)
4. The ability to stretch and bend before returning to its normal shape and size when forces are removed. E.g. Liquid silicon rubber teat (10)
6. How closely packed the material is, its relative mass per unit volume, e.g. HIPS-expanded PS (7)
7. Ability to resist twisting, e.g. glass or concrete (9, 8)
8. The ability to withstand force without breaking or permanently bending or deforming (8)

2. Opaque (no light), translucent (some light) and transparent (all light passes through) (7, 10)
3. Can be drawn out under tension before fracturing (e.g. deep drawing). E.g. aluminium can (9)
5. The ability to withstood wear, tear, weathering and deterioration through corrosion, decay and degrading. E.g. kevlar protective pads (10)
9. The ability of being magnetized or attracted by a magnet, e.g steel, but not mild steel or stainless steel (9)
10. The ability to withstand abrasive wear and indentation or deformation, hardness leads to brittleness. E.g. diamond, die steel drill bits (8)
