Vickers is only used for metals (far as I can tell). As for the values you wish to find, look on Mindat.org

Is there a formula to calculate metal strength by thickness?
Yes - there are many different formulae but the relationship of hardness to tensile or yield strength is at best very approximate. There is a general increase in hardness with increasing strength for most metals - where hardness has been measured by an indentation method such as Brinell.
Do types define a set of values and a set of operations that can be applied on the values?
Yes.
What are the gospel values?
gospel values are love faith peace justices mission and also prayer
How many method used to collect values in a form in php?
POST, GET & REQUEST will get the values from a form.
Can you store unlimited value in any integer type of variables?
No. In Java, you can store a limited range of values in an integer. Specifically, integers are 32-bit signed values which can store values in the range [-231, 231-1]. If you need to store more values, consider using a long integer [-263, 263-1] or the BigInteger class (which can store arbitrary-precision values).
Why was Freidrich Mohs work important?
Mohs created the Mineral Hardness scale in 1822. It is a comparison table showing 10 common minerals and their relative hardness values. Scientists can use it to compare to other unknown minerals and for classification of minerals. In science you always want to be able to compare something to something else. So instead of saying something is soft or hard, the Mohs Scale gives a relative value to the description.
What are you referring when you address the hardness of a mineral?
A minerals hardness is basically its tendency to scratch or be scratched by another mineral or object. For example if a mineral is very soft (Like Talc or Gypsum) then you can scratch it with your finger but if you have a very hard mineral such as diamond you will not be able to scratch it with anything other than another diamond. The hardness values are quantified in Mohs hardness scale using the numbers 1-10 with 1 being the softest (Talc) and 10 being the hardest (Diamond). Ordinary objects with a known hardness can be used to determine a minerals relative hardness by simply seeing if the object will scratch the mineral or not. Pencil lead=1.5, Fingernail =2.2-2.5, Penny=3.2-3.5, Pocketknife=5.1, Glass plate=5.5, Steel file=6.5, Streak plate=7.0
The hardness of iron?
It's actually a rather difficult question to answer as iron can be forged in a number of different ways, each giving a different hardness. I've attached a link to a site giving different hardness values for some treatments of grey iron.
Why different materials have different hardness values?

What is the hardest mineral and what is its hardness on the Mohs scale?
Answer 1Mohs Hardness Scale is a comparative way of measuring the hardness of a rock or mineral - that is, its resistance to scratching. It is usually used with minerals because rocks tend to have a heterogeneous consistency and therefore varying degrees of hardness.The Mohs scale goes from 1 to 10, with one being the softest mineral and ten being the hardest. There are minerals that are considered "indicators" and are known to have a specific, constant hardness value. These indicator minerals, with their hardness values, are:Talc: 1 (softest)Gypsum: 2Calcite: 3Fluorite: 4Apatite: 5Feldspar: 6Quartz: 7Topaz: 8Corundum: 9Diamond: 10 (hardest)A set of common objects with known hardness values is often used to estimate the hardness of an unknown sample, by attempting to scratch it. The average human fingernail has a hardness of 2.5 and a copper penny has a hardness of 3.5. A stainless steel blade is about 6.5 and a section of average window glass is approximately 5.5._______________________________________________________Answer 2The Mohs scale of mineral hardness is based on the ability of one natural sample of matter to scratch another mineral. The samples of matter used by Mohs are all different minerals. Minerals are pure substances found in nature.1 = talcum, softest10= diamond, hardestFurther reading via 'Related links'A Mohs hardness scale is a graph. This graph shows information on the body and the hardness.
What are some properties of rock?
Hardness, resistance to weathering, texture, mineral composition, color, and porosity.
What is the name for nonmetallic minerals that are values for their beauty and rarity rather than their usefulness?
gemstones
What is the hardness of stellite in rockwell?
In depends on the hardfacing technique and the final Fe dilution. Typical values range 42-45 HRC.
What is the mohs value for an igneous rock?
"Igneous" is a general classification, not a specific type of rock. The hardness values vary depending on the exact composition.
What property are you testing if you scratch a mineral with a penny a nail and your fingernail?
It relative hardness, compared to others. It is relative because it does not give absolute values.
How can you improve upon the crayon invention?
It has already been improved. Pencils have many colors and hardness values. Pens are a type of pencil with ink instead of graphite.
