Question d
Describe any two of the following metal properties: (i) Malleability, (ii) Elasticity, (iii) Brittleness.
Worked Solution & Example Answer:Describe any two of the following metal properties: (i) Malleability, (ii) Elasticity, (iii) Brittleness. - Leaving Cert Engineering - Question d - 2009
Step 1
Malleability
Answer
Malleability is defined as the ability of a metal to be deformed under compression. This means that metals can be hammered or rolled into thin sheets without breaking. This property is crucial for metalworking processes such as forging and extrusion, where the metal is manipulated into desired shapes while maintaining structural integrity.
Step 2
Elasticity
Answer
Elasticity refers to a metal's ability to return to its original shape after being subjected to external forces that cause distortion. When a force is applied, the metal deforms; however, if the force is removed and the deformation does not exceed the elastic limit, the metal will regain its original form. This property is essential for materials that must endure repeated stresses without permanent deformation.
