How are engineering materials classified?
the material usually classified based on their properties.
What is the dilemma between design and manufacturing in terms of mechanical properties?
the achieve design function and quality the material must be strong for ease of manufacturing,the material should not be strong in general...
How can you calculate weight if you have given area and thickness?
you need to know the desnsity of the material (grams per cubic centimeter or pounds per cubic inch). Then multiply density times area times thickness to get weight with proper units. Weight = density x volume
What would happen to the physical properties of a cold worked material if it were fully annealed and cold worked further?
It would have approximately the same characteristics of the material before it was annealed. In other words, it would almost be the same as the first time it was cold worked, assuming nothing was done to the material before it was cold worked the first time.
What is mean by yield strength of steel?
The steel has a ductile material properties so that it could be elongate at a point of ultimate yield point.It is stable while before the break point
Are pH and density physical properties?
* pH is a chemical property of a solution.* density is a physical property of any material.
Density is an example of?
Mass, volume, and density are all example of physical properties. Physical properties are any characteristic of a substance that can be observed or measured without changing the material.
What is a physical properties of a material?
there are 4 main types of physical properties 1. Appearance 2. luster 3.Density 4.colour
What would be the destiny if you had a sample of the same material that was half the size?
Same density. Density is a property of the material and is independent of how much there is of it. That's why properties are important. Now the destiny of that material...I imagine it will eventually end up in a land-fill.
The magnetic properties of a material depend on its?
The magnetic properties of a material depend on its atomic structure.
Are properties such odor color density and solubility physical or chemical properties?
Color and density are physical properties. Odor and solubility are chemical properties.
Is density a physical?
Density is physical properties
What are some examples of intensive properties?
Examples are temperature, color, hardness, melting point, boiling point, pressure, molecular weight, and density. Because intensive properties are sometimes characteristic of a particular material, they can be helpful as clues in identifying unknown substances.
What properties are volume mass and length?
density ductility reactivity weight
What is the difference between the chemical and physical properties for sodium chloride?
For all materials physical properties are related to some characteristics as density, hardness, refractive index etc. and the chemical properties are related to some characteristics as chemical reactivity, flammability, oxydation etc. Physical properties are characterized by getting back the original material by changing its form, state, etc. Chemical properties are characterized by a complete change in the material itself i.e. you cannot get back the same material.
What can you infer about the density of a material if a sampleof it floats in water?
That the material's density is less than the density of water.
Why mechanical properties of solid important for design of machines and structures?
One cannot design any machine or structure properly without knowledge of the material physical properties of the materials. Key properties are strength, density, modulus, thermal expansion, and conductivity.
