What is engineering material and its properties?
Physical Properties of Materials Physical properties of material are those which can be observed without change of identity of material. Physical properties of metals are density, color, size and shape, specific gravity of material, porosity etc. Some of these are defined as below.
What are engineering properties?
Engineering properties, considered broadly, are physical, chemical, and biological characteristics that are observable, measureable, and influence behavior to the extent that they are important in engineering analyses and design, and in performance of components, systems, or processes.
How many properties of materials are there?
A commonly talked about property is the state or phase of matter. There are currently five different states of matter that have been identified: solids, liquids, gases, plasma and Bose-Einstein condensate. The last two of these are much less well known.

What are the material properties of steel?
Steel has a number of properties, including: hardness, toughness, tensile strength, yield strength, elongation, fatigue strength, corrosion, plasticity, malleability and creep.
What are the properties of design engineering?
Design engineers tend to work on products and systems that involve adapting and using complex scientific and mathematical techniques. The emphasis tends to be on utilizing engineering physics and other applied sciences to develop solutions for society.
How can the properties of steel be improved?
The strength of steel can be increased by the addition of alloys such as manganese, niobium and vanadium. However, these alloy additions can also adversely affect other properties, such as ductility, toughness and weldability . The more steel is rolled, the stronger it becomes.
What mean properties?
Property is any item that a person or a business has legal title over. Property can be tangible items, such as houses, cars, or appliances, or it can refer to intangible items that carry the promise of future worth, such as stock and bond certificates.
