properties

Question 1

compressive strength

Answer 1

Ability to withstand being crushed or shortened by pushing forces (e.g., - Bridge - concrete, steel- stool legs)

Question 2

tensile strength

Answer 2

Ability to resist stretching or pulling forces (tension) (e.g.,- rope, fabrics, cable - suspension bridge - low carbon steel)

Question 3

shear strength

Answer 3

The ability to resist sliding forces on a parallel plane (scissors)

Question 4

bending strength

Answer 4

The ability to resist sliding forces on that may bend the material (e.g.,- support beams - cast iron/steel)

Question 5

torsional strength

Answer 5

Ability to withstand twisting forces from applied torque or torsion (timber beam - oak,metal)

Question 6

hardness

Answer 6

Ability to resist abrasive wear such as scratching, surface indentation or cutting (stainless steel)

Question 7

toughness

Answer 7

Ability to absorb impact force without fracture (e.g., - kevlar, phone cases)

Question 8

plasticity

Answer 8

Ability to permanently deformed (shaped) and retain the deformed shape (concrete, building support, plastic wrap)

Question 9

ductility

Answer 9

Ability to be drawn out under tension, reducing the cross-sectional area without cracking (i.e., - stretching material into a wire: gold, silver, copper etc.)

Question 10

malleability

Answer 10

Withstanding deformation by compression without cracking (increases with a raise in temp.) (e.g., - aluminium, tin foil)

Question 11

elasticity

Answer 11

Ability to be deformed and then return to original shape (when the force is removed) (i.e., - rubber)
