Question d
Explain any two of the following metal properties: (i) Toughness, (ii) Ductility, (iii) Melting point.
Worked Solution & Example Answer:Explain any two of the following metal properties: (i) Toughness, (ii) Ductility, (iii) Melting point. - Leaving Cert Engineering - Question d - 2012
Step 1
Toughness
Answer
Toughness is defined as the ability of a material to withstand an impact or hammering load without fracturing. It is a critical property in applications where the material will experience sudden forces or impacts, ensuring that it can absorb energy and deform plastically before breaking.
Step 2
Ductility
Answer
Ductility refers to the capability of a metal to be drawn into wires. A ductile material can be permanently stretched by a tensile force without fracturing. This property is essential for materials used in applications where elongation and shaping are necessary, such as in the manufacturing of wires and cables.
