Question d
Explain any two of the following metal properties: (i) Britleness, (ii) Melting point, (iii) Toughness, (iv) Elasticity.
Worked Solution & Example Answer:Explain any two of the following metal properties: (i) Britleness, (ii) Melting point, (iii) Toughness, (iv) Elasticity. - Leaving Cert Engineering - Question d - 2022
Step 1
Explain (i) Britleness
Answer
Britleness refers to a material's tendency to break or shatter when subjected to stress, particularly under impact. A brittle material does not deform plastically and will fracture instead. Common examples of brittle materials include cast iron, glass, and concrete, which exhibit this property by breaking upon impact or excessive force.
Step 2
Explain (ii) Melting point
Answer
The melting point of a metal is the specific temperature at which it changes from a solid state to a liquid state. This physical property is crucial in the manufacturing and processing of metals, as it determines the conditions needed for melting and shaping the material into desired forms.
