mechanical properties of materials

Question 1

compressive strength

Answer 1

the ability to withstand being crushed or shortened by pushing forces

Question 2

tensile strength

Answer 2

the ability to resist stretching or pulling forces

Question 3

bending strength

Answer 3

the ability to resist forces that may bend the material

Question 4

shear strength

Answer 4

the ability to resist sliding forces on a parallel plane

Question 5

torsional strength

Answer 5

the ability to withstand twisting forces from applied torque or torsion

Question 6

hardness

Answer 6

the ability to resist abrasive wear such as scratching, surface indentation or cutting

Question 7

toughness

Answer 7

the ability to absorb impact force without fracture

Question 8

plasticity

Answer 8

the ability to be permanently deformed and retain the deformed shape

Question 9

ductility

Answer 9

the ability to be drawn out under tension, reducing the coss-sectional area without cracking for example stretching a material into a wire

Question 10

malleability

Answer 10

the ability to withstand deformation by compression without cracking
malleability increases with a rise in temperature

Question 11

elasticity

Answer 11

the ability to be deformed and then return to its original shape when the force is removed
