Question d
Explain any two of the following metal properties: (i) Conductivity, (ii) Brittleness, (iii) Toughness.
Worked Solution & Example Answer:Explain any two of the following metal properties: (i) Conductivity, (ii) Brittleness, (iii) Toughness. - Leaving Cert Engineering - Question d - 2018
Step 1
(i) Conductivity
Answer
Conductivity is the ability of a material to allow heat or electrical current to pass through it. Metals are typically good conductors due to the presence of free-moving electrons within their structure. This characteristic makes them essential in electrical applications and thermal management, allowing for efficient energy transfer.
Step 2
(ii) Brittleness
Answer
Brittleness refers to the inability of a material to withstand impact; a brittle material will fracture or shatter when subjected to a sudden force or blow. This property is contrasted with ductility, where materials can deform without breaking. Brittle metals may fail suddenly, which is vital to consider in structural applications.
