Question c
Explain any two of the following metal properties: (i) Brittleness, (ii) Ductility, (iii) Malleability.
Worked Solution & Example Answer:Explain any two of the following metal properties: (i) Brittleness, (ii) Ductility, (iii) Malleability. - Leaving Cert Engineering - Question c - 2007
Step 1
Explain (i) Brittleness
Answer
Brittleness is a property of a material that makes it prone to fracture when subjected to stress or impact, rather than deforming plastically. Brittle materials are typically very hard and lack the ability to absorb energy, leading to sudden failure when a force is applied. An example of a brittle material is glass, which can shatter under impact.
Step 2
Explain (ii) Ductility
Answer
Ductility refers to the ability of a metal to be drawn into a wire. This property allows metals to undergo significant plastic deformation before fracturing. A ductile material can be stretched under tensile forces without breaking, making it highly useful in various applications where flexibility is required.
