5 Questions
Define ductility and provide an example of a ductile material.
Ductility is the measure of the amount of permanent deformation a material can undergo under tensile force without fracture. An example of a ductile material is mild steel.
What is the property opposite to ductility and provide an example of a brittle material?
The property opposite to ductility is brittleness. An example of a brittle material is cast iron.
Explain resilience and how it is measured on a stress-strain curve.
Resilience is the ability of the material to absorb energy when deformed elastically and return it when unloaded. It is measured as the area under the stress-strain curve till the elastic point.
What is the measure of the resistance offered by a material to penetration when a compressive force is applied?
Hardness is the measure of the resistance offered by a material to penetration when a compressive force is applied.
List the types of strength and provide a brief definition for each type.
The types of strength are: 1. Tensile strength: resistance to stretching force 2. Compressive strength: resistance to crushing force 3. Shear strength: resistance to sliding force 4. Bending strength: resistance to bending force 5. Torsion strength: resistance to twisting force.
Test your knowledge of mechanical properties with a focus on ductility and brittleness. Learn about the behavior of materials under tensile force and their ability to withstand deformation.
