Question d
Describe any two of the following material properties: (i) Brittleness, (ii) Malleability, (iii) Conductivity.
Worked Solution & Example Answer:Describe any two of the following material properties: (i) Brittleness, (ii) Malleability, (iii) Conductivity. - Leaving Cert Engineering - Question d - 2011
Step 1
Brittleness
Answer
Brittleness is a material property characterized by the inability of a material to deform plastically before fracture. A brittle material will crack or break under stress rather than stretch or deform. For example, glass is often cited as a brittle material, as it can easily fracture when subjected to an impact.
Step 2
Malleability
Answer
Malleability refers to a material's ability to deform under compressive stress without breaking. This property allows materials to be shaped into thin sheets by processes like rolling or hammering. Generally, metals exhibit high malleability, and their malleability can be enhanced by heating them.
