Statements (I): Ductile materials generally absorb more impact energy than the brittle materials.
Statements (II): Ductile material generally have higher ultimate strength than brittle materials.

Question 3

Malleability is the property by which material can

Question 4

Stress-strain curves are an important graphical measure of material’s mechanical properties. It is seen that strain energy increases quadratically with the stress or strain; i.e. that as the strain increases the energy stored by a given increment of additional strain grows as the square of the strain.
