Explain any two of the following metal properties: (i) Elasticity, (ii) Toughness, (iii) Conductivity.
Worked Solution & Example Answer:Explain any two of the following metal properties: (i) Elasticity, (ii) Toughness, (iii) Conductivity. - Leaving Cert Engineering - Question d - 2014
Step 1
Elasticity
Answer
Elasticity is defined as the ability of a material to return to its original shape after being deformed by an external force. When a force distorts the shape of the material, it stores potential energy, and upon the removal of the force, it releases this energy, allowing the material to revert to its initial form. A relevant example of an elastic material is rubber, which can stretch and then return to its original dimensions.
Step 2
Toughness
Answer
Toughness is the property of a material that enables it to absorb energy and withstand impacts without fracturing. This attribute is crucial for materials that are subject to sudden forces, as it allows them to endure shocks and stresses. Steel is a prime example of a tough material, which can absorb significant energy while sustaining its structural integrity.
