DT properties

• Strength is the ability of a material to withstand compression, tension and shear, for example, in woven fabrics cotton isn’t as strong as wool when pulled.
• Hardness is the ability to withstand impact without damage, for example, pine is easier to dent with an impact than oak; therefore, oak is harder.
• Toughness refers to materials that are hard to break or snap, and can absorb shock, for example, Kevlar in bulletproof vests is a very tough material.
• Malleability is the ability to bend or shape easily, making a material easily malleable, for example, sheet metal such as steel or silver is malleable and can be hammered into shape.
• Ductility is the ability to be stretched, making a material ductile, for example, pulling copper into wire shows it is ductile.
• Elasticity is the ability to be stretched and then return to its original shape, for example, elastane in swimming costumes is a highly elastic material.
