Mechanical Properties of Materials

Question 1

Compressive strength

Answer 1

The ability to withstand being crushed or shortened by pushing forces (compression)

Question 2

Tensile strength

Answer 2

The ability to resist stretching or pulling forces (tension)

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 (shaped) and retain the deformed shape

Question 9

Ductility

Answer 9

The ability to be drawn out under tension, reducing the cross sectional area without cracking, for example stretching a metal 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 the original shape when the force is removed

Question 12

What is meant by mechanical property of a material?

Answer 12

Mechanical properties are associated to how a material reacts with external forces
