1 - Materials and their applications - Mechanical Properties

Question 1

Compressive strength

Answer 1

Ability to withstand being crushed (compressed)

Question 2

Tensile strength

Answer 2

Ability to resist stretching/ pulling forces (tension)

Question 3

Bending strength

Answer 3

Ability to resist forces which may bend the material

Question 4

Shear strength

Answer 4

Ability to resist sliding forces on a parallel plane

Question 5

Torsional strength

Answer 5

Ability to withstand twisting forces from applied torque or torsion

Question 6

Hardness

Answer 6

Ability to resist abrasive wear such as scratching, indentation or cutting

Question 7

Toughness

Answer 7

Ability to absorb force without fracture

Question 8

Plasticity

Answer 8

Ability to be deformed/ shaped and retain the new deformed shape

Question 9

Ductility

Answer 9

The ability of a material to be stretched, pulled, or drawn into a thin wire or thread without cracking or breaking

Question 10

Malleability

Answer 10

The ability to withstand deformation by compression without cracking. Malleability increases as temperature increases

Question 11

Elasticity

Answer 11

The ability to be deformed and then return to its original shape once the force has been removed
