Materials and Properties Flashcards
Why is it important to know the properties of the materials?
Properties must be known so suitable materials may be picked for the product.
Why is it important to consider the cost of the materials?
They must be considered as the materials must not exceed budget while not compromising on other factors.
Why is it important to consider the availability of the materials?
They must be considered as sourcing locally will help local economy and will be cheaper.
Why is it important to consider the volume of production?
Must be considered as some materials may be more suitable for mass manufacturing.
Why is it important to consider the environmental issues?
Must be considered as certain materials may be recycled or reused.
Why is it important to consider the complexity of products or components?
Must be considered as certain materials are easier to work with (easily formed or moulded).
Why is it important to consider the performance of products or components?
It must be considered as different products will have different lifespans, be used in different conditions and will have varying levels of maintenance required.
What are the acoustic properties of a material?
It is the ability to absorb and transfer sound.
What are the chemical properties of a material?
How a material reacts to corrosion and chemicals.
What are the electrical properties of a material?
How a material conducts or resists electrical currents.
What are the optical properties of a material?
The ability of the material to transmit and reflect light.
What are the physical properties of a material?
The size, density, surface texture and aesthetic qualities.
What are the thermal properties of a material?
The ability of the material to transmit, resist and transfer heat energy.
What are the mechanical properties of a material?
How a material reacts with physical forces.
What is the mechanical property of strength in a material?
It is the ability of the material to withstand tensile, compressive or sheer force without permanently deforming.
What is the mechanical property of toughness in a material?
It is the ability of a material to withstand a sudden impact without fracturing.
What is the mechanical property of brittleness in a material?
It is the opposite of toughness as this is how easily the material fractures.
What is the mechanical property of hardness in a material?
It is the ability of the material to resist scratching, abrasion and wear.
What is the mechanical property of stiffness in a material?
It is the ability of a material to withstand deformation under an applied force.
What is the mechanical property of elasticity in a material?
The ability of a material to return to its original shape after an applied force is removed.
What is the mechanical property of ductility in a material?
It is the ability of a material to be deformed permanently by stretching, bending or twisting.
What is the mechanical property of malleability in a material?
It is the ability of a material to be deformed by compressive forces without fracturing.
