Question d
Describe any two of the following material properties: (i) Brittleness (ii) Ductility (iii) Toughness.
Worked Solution & Example Answer:Describe any two of the following material properties: (i) Brittleness (ii) Ductility (iii) Toughness. - Leaving Cert Engineering - Question d - 2016
Step 1
(i) Brittleness
Answer
Brittleness is the inability of a material to withstand impact. A brittle material will fracture if subjected to an impact or blow, meaning it cannot absorb significant energy before failing. This property is crucial in applications where materials need to endure dynamic loads, as brittleness can lead to sudden and catastrophic failures.
Step 2
(ii) Ductility
Answer
Ductility refers to the ability of a material to be stretched into a wire without breaking. This property is vital for metals used in electrical wiring and structural applications, where a metal must be pliable enough to undergo deformation yet strong enough to maintain load-bearing capabilities without fracture.
